Paper No. #940 N1 - Last updated - 2010-05-03 ER - TY - JOUR T1 - Intracellular localization of a group II chaperonin indicates a membrane- related function AN - 19254737; 5831684 AB - Chaperonins are protein complexes that are believed to function as part of a protein folding system in the cytoplasm of the cell. We observed, however, that the group II chaperonins known as rosettasomes in the hyperthermophilic archaeon Sulfolobus shibatae, are not cytoplasmic but membrane associated. This association was observed in cultures grown at 60 degree C and 76 degree C or heat-shocked at 85 degree C by using immunofluorescence microscopy and in thick sections of rapidly frozen cells grown at 76 degree C by using immunogold electron microscopy. We observed that increased abundance of rosettasomes after heat shock correlated with decreased membrane permeability at lethal temperature (92 degree C). This change in permeability was not seen in cells heat-shocked in the presence of the amino acid analogue azetidine 2-carboxylic acid, indicating functional protein synthesis influences permeability. Azetidine experiments also indicated that observed heat-induced changes in lipid composition in S. shibatae could not account for changes in membrane permeability. Rosettasomes purified from cultures grown at 60 degree C and 76 degree C or heat-shocked at 85 degree C bind to liposomes made from either the bipolar tetraether lipids of Sulfolobus or a variety of artificial lipid mixtures. The presence of rosettasomes did not significantly change the transition temperature of liposomes, as indicated by differential scanning calorimetry, or the proton permeability of liposomes, as indicated by pyranine fluorescence. We propose that these group II chaperonins function as a structural element in the natural membrane based on their intracellular location, the correlation between their functional abundance and membrane permeability, and their potential distribution on the membrane surface.

[Part 1 of 1] T2 - ENHANCED EVALUATION OF CUMULATIVE EFFECTS ASSOCIATED WITH US ARMY CORPS OF ENGINEERS PERMITTING ACTIVITY FOR LARGE-SCALE DEVELOPMENT IN COASTAL MISSISSIPPI. AN - 36346564; 10526-030550_0001 AB - PURPOSE: The establishment of a plan for enhanced evaluation of cumulative effects associated with US Army Corps of Engineers permitting activity for large-scale development in coastal areas in Mississippi is proposed. The areas affected include those along the Gulf Coast of Harrison, Hancock, and western Jackson counties. This EIS is a hybrid document with a cope that departs in several notable ways from a traditional analysis under the National Environmental Policy Act. The scope is two-fold: 1) to produce a comprehensive analysis of recent and reasonably foreseeable development trends and associated environmental conditions and 2) to consider effects of putting into place a tailored method for evaluating and mitigating regional cumulative effects in environmental impact evaluations associated with future permit applications for large-scale development projects in coastal Mississippi. The trends analysis associated with this EIS evaluates relevant planning documents and projects in coastal Mississippi development trends and their cumulative effects spanning the period extending from 1992 to 2020, using geographic information systems and econometric forecasting models. The EIS evaluates long-term (20-year) regional cumulative effects of Corps permitting actions in the coastal Mississippi area under various development scenarios and regulatory frameworks. For the proposed action, the EIS assesses the environmental and socioeconomic effects of developing and implementing a consistent methodology for conducting cumulative effects analyses that would rely on the results of the trends analysis in future Corps permit decisions regarding applications for large-scale development projects in coastal Mississippi that require individual Corps permits. Four growth scenarios were evaluated to assess the future environmental and socioeconomic conditions of the coastal Mississippi area. Under the No Action Alternative, the Corps would continue to perform cumulative effects analyses for permits on an ad hoc basis, and regional growth would continue to be managed as in the past. Under the proposed action, mitigation strategies (termed Regional Conservation Practices (RCPs) in the EIS) would be considered during permitting and implementation of large-scale developments. These RCPs would encompass cumulative effects identified through trend analyses including enhanced stormwater control measures, enhanced management strategies and net technology for reducing septic tank failures, enhanced wetland creation and mitigation tracking, and increased intervention for the protection of federally protected species. POSITIVE IMPACTS: Under the proposed action, enhanced consideration of regional cumulative effects during permitting and implementation of RCPs to reduce these effects would result in minor to significant beneficial effects relative to the No Action Alternative. It would be noted that most of these RCPs are beyond the regulatory authority of the Corps; hence, many RCPs would need to be adopted voluntarily by state, local, and/or private developers, others might be included as special permit conditions by the Corps for large-scale development projects, on a case-by-case basis. Relative to current conditions, implementation of the proposed action might mitigate significant adverse effects on most resources, even under high-growth scenario conditions. NEGATIVE IMPACTS: Regardless of the permitting regime established, large-scale developments would result in the loss of valuable coastal wetlands and associated wildlife habitat and other ecosystem values. Such impacts would reduce the economic viabilities of commercial sectors dependent on wetland values. Due to the demographics of coastal areas, large-scale projects could disproportionately impact low-income, elderly, and ethnic minority groups. Developments in areas prone to hurricanes and other storm-related flooding would also affect the level of public safety. Cultural and visual resources would also be degraded by virtually any extensive development.

However, the contribution of NEP inhibition to their effects is not yet fully understood. To address the role of cardiac NEP inhibition in the anti-remodeling effects of a vasopeptidase inhibitor, we examined the effects of omapatrilat on the development of cardiac remodeling in rats with left coronary artery ligation (CAL) and those on collagen synthesis in cultured fibroblast cells. In vivo treatment with omapatrilat (30 mg/kg/day for 5 weeks) inhibited cardiac NEP activity in rats with CAL, which was associated with a suppression of both cardiac hypertrophy and collagen deposition. In cultured cardiac fibroblasts, omapatrilat (10^sup -7^~10^sup -5^ M) inhibited NEP activity and augmented the ANP-induced decrease in [^sup 3^H]-proline incorporation. ONO-BB, an active metabolite of the NEP selective inhibitor ONO-9902, also augmented the ANP-induced response, whereas captopril, an ACE inhibitor, did not. The angiotensin I-induced increase in [^sup 3^H]-proline incorporation was prevented by omapatrilat and captopril, but not by ONO-BB. The results suggest that vasopeptidase inhibitor suppressed cardiac remodeling in the setting of chronic heart failure, possibly acting through the direct inhibition of cardiac NEP. Vasopeptidase inhibitors may have therapeutic advantages over the classical ACE and NEP inhibitors alone with respect to the regression of cardiac fibrosis.[PUBLICATION ABSTRACT] JF - Molecular and Cellular Biochemistry AU - Maki, Toshiyuki AU - Nasa, Yoshihisa AU - Tanonaka, Kouichi AU - Takahashi, Masaya AU - Takeo, Satoshi Y1 - 2003/12// PY - 2003 DA - Dec 2003 SP - 265 EP - 73 CY - New York PB - Springer Science & Business Media VL - 254 IS - 1-2 SN - 03008177 KW - Biology--Cytology And Histology KW - Cardiovascular Agents KW - Protease Inhibitors KW - Pyridines KW - Thiazepines KW - omapatrilat KW - Collagen KW - DNA KW - Proline KW - Neprilysin KW - Heart failure KW - Rodents KW - Animals KW - Collagen -- metabolism KW - Dose-Response Relationship, Drug KW - Fibrosis KW - DNA -- metabolism KW - Fibroblasts -- metabolism KW - Rats KW - Proline -- metabolism KW - Cells, Cultured KW - Rats, Wistar KW - Thiazepines -- pharmacology KW - Time Factors KW - Pyridines -- pharmacology KW - Cardiovascular Agents -- pharmacology KW - Male KW - Protease Inhibitors -- pharmacology KW - Heart Failure -- drug therapy KW - Ventricular Remodeling -- drug effects KW - Neprilysin -- antagonists & inhibitors UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/756177162?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ahealthcompleteshell&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Molecular+and+Cellular+Biochemistry&rft.atitle=Direct+inhibition+of+neutral+endopeptidase+in+vasopeptidase+inhibitor-mediated+amelioration+of+cardiac+remodeling+in+rats+with+chronic+heart+failure&rft.au=Maki%2C+Toshiyuki%3BNasa%2C+Yoshihisa%3BTanonaka%2C+Kouichi%3BTakahashi%2C+Masaya%3BTakeo%2C+Satoshi&rft.aulast=Maki&rft.aufirst=Toshiyuki&rft.date=2003-12-01&rft.volume=254&rft.issue=1-2&rft.spage=265&rft.isbn=&rft.btitle=&rft.title=Molecular+and+Cellular+Biochemistry&rft.issn=03008177&rft_id=info:doi/10.1023%2FA%3A1027337601863 LA - English DB - ProQuest Central N1 - Copyright - Kluwer Academic Publishers 2003 N1 - Last updated - 2014-08-22 DO - http://dx.doi.org/10.1023/A:1027337601863 ER - TY - JOUR T1 - Thinning of the Patagonian icefields from recent laser altimetry, SRTM and earlier cartographic data AN - 742927656; 2010-060927 JF - Eos, Transactions, American Geophysical Union AU - Casassa, Gino AU - Rivera, Andres AU - Rignot, Eric AU - Thomas, Robert AU - Acuna, Cesar AU - Brecher, Henry AU - Frederick, Earl AU - Krabill, William AU - Manizade, Serdar AU - Russell, Robert AU - Sonntag, John AU - Swift, Robert AU - Yungel, James AU - Anonymous Y1 - 2003/12// PY - 2003 DA - December 2003 SP - Abstract C11C EP - 0821 PB - American Geophysical Union, Washington, DC VL - 84 IS - 46, Suppl.

AN - 71588355; 15136753 AB - We investigated the difference in cell-killing effect and mutation induction between carbon- and neon-ion beams in normal human cells. Carbon- and neon-ion beams were accelerated by the Riken Ring Cyclotron (RRC) at the Institute of Physical and Chemical Research in Japan. Cell-killing effect was measured as the reproductive cell death using the colony formation assay. Mutation induction at the HPRT locus was detected to measure 6-thioguanine-resistant clones. The mutation spectrum of the deletion pattern of exons of induced mutants was analyzed using the multiplex polymerase chain reaction (PCR). Cell-killing effect was almost the same between carbon- and neon-ion beams with similar linear energy transfer (LET) values, while there observed a large difference in mutation frequency. Furthermore, in the case of neon-ion beams 60% of mutants showed total deletions and 35-40% showed partial deletions, while 95-100% of carbon-ion induced mutants showed total deletions. The results suggest that different ion species may cause qualitative and quantitative difference in mutation induction even if the LET values are similar.

AN - 71543800; 15008196 AB - Space flight is associated with an increase of peroxidative damage after returning to 1 g. The effect is more pronounced after long-duration space flight and can even last for several weeks after landing. In humans there is increased lipid peroxidation in erythrocyte membranes, reduced blood antioxidants, and increased urinary excretion of 8-iso-prostaglandin F2alpha, and 8-oxo-7, 8 dihydro-2 deoxyguanosine. Isoprostane 8-iso-prostaglandin F2alpha and 8-oxo-7, 8 dihydro-2 deoxyguanosine are markers for oxidative damage to lipids and DNA, respectively. The changes are attributed to a combination of energy deficiency that occurs during flight and substrate competition for amino acids occurring between repleted muscle and other tissues during the recovery phase. The observations in humans have been complemented by studies in rodents, which showed increased production of lipid peroxidation products and decreased antioxidant enzyme activity afterflight. The changes in rodents were attributed to the stress associated with re-entry into Earth's gravity. Reducing the imbalance between the production of endogenous oxidant defenses and oxidant production by increasing the supply antioxidants in diet may lessen the severity of the postflight increase in oxidative stress.

For instance, land-surface temperature data have been available for many years, and satellite precipitation data are becoming available at ever-increasing space and time resolutions. In addition, a number of platforms provide snow and vegetation parameters of increasing sophistication, and satellite missions targeted at measuring near-surface soil moisture are expected before the end of the decade. However, current hydrologic remote sensing analysis and interpretation tools may not be adequate due to little use of such data until recent years. This can be attributed to an emphasis on atmospheric rather than hydrologic remote sensing missions, a relative immaturity of retrieval algorithms for deriving hydrologic information from remote sensing observations, hydrologic models that are unsuitable for ingesting remote sensing information, and a limited understanding of the techniques to objectively improve and constrain hydrologic models by assimilating remote sensing data.

Four examples are shown in SeaWiFS data at that location. Similar plumes are found in many locations over the globe. The direction of propagation of plumes from the source depends on the synoptic situation. Plumes travel both northwards, reaching the Mediterranean Sea, and southwards, to the interior of the Sahara. Such plumes may ultimately assemble into massive dust palls that frequently travel long distances out of North Africa.

The best agreement with historical and proxy data is obtained using both forcings, each of which has a significant effect on global mean temperatures. However, their regional climate impacts in the Northern Hemisphere are quite different. While the short-term continental winter warming response to volcanism is well known, it is shown that due to opposing dynamical and radiative effects, the long-term (decadal mean) regional response is not significant compared to unforced variability for either the winter or the annual average. In contrast, the long-term regional response to solar forcing greatly exceeds unforced variability for both time averages, as the dynamical and radiative effects reinforce one another, and produces climate anomalies similar to those seen during the Little Ice Age. Thus, long-term regional changes during the preindustrial appear to have been dominated by solar forcing.

Separate Fe-, Mn-, and Cu-containing SHA materials along with a transition-metal free SHA (pure-SHA) were synthesized using a precipitation method. Chemical and mineralogical analyses determined if and how Fe, Mn, and Cu were incorporated into the SHA structure. X-ray diffraction (XRD), Rietveld refinement, and transmission electron microscopy (TEM) confirmed that SHA materials with the apatite structure were produced. Chemical analyses indicated that the metal containing SHA materials were deficient in Ca relative to pure-SHA. The shift in the infrared PO4-3 vibrations, smaller unit cell parameters, smaller particle size, and greater structural strain for Fe-, Mn-, and Cu-containing SHA compared with pure-SHA suggested that Fe, Mn, and Cu were incorporated into SHA structure. Rietveld analyses revealed that Fe, Mn, and Cu substituted into the Ca(2) site of SHA. An Fe-rich phase was detected by TEM analyses and backscattered electron microscopy in the Fe-containing SHA material with the greatest Fe content. The substitution of metals into SHA suggests that metal-SHA materials are potential slow-release sources of micronutrients for plant uptake in addition to Ca and P.

If this organic matter were produced by aqueous alteration of elemental (graphitic or amorphous) carbon on an asteroid, then we would expect to see the organic matter occurring preferentially in interplanetary materials that exhibit evidence of aqueous activity, such as the presence of hydrated silicates. On the other hand, if the organic matter were produced either during the nebula phase of Solar System evolution or in the interstellar medium, we might expect this organic matter to be incorporated into the dust as it formed. In that case pre-biotic organic matter would be present in both the anhydrous and the hydrated interplanetary materials. We have performed carbon X-ray absorption near-edge structure spectroscopy and infrared spectroscopy on primitive anhydrous and hydrated interplanetary dust particles (IDPs) collected by NASA from the Earth's stratosphere. We find that organic matter is present in similar types and abundances in both the anhydrous and the hydrated IDPs, and, in the anhydrous IDPs some of this organic matter is the "glue" that holds grains together. These measurements provide the first direct, experimental evidence from the comparison of extraterrestrial samples that the bulk of the pre-biotic organic matter occurs in similar types and abundances in both hydrated and anhydrous samples. This indicates that the bulk of the pre-biotic organic matter in the Solar System did not form by aqueous processing, but, instead, had already formed at the time that primitive, anhydrous dust was being assembled. Thus, the bulk of the pre-biotic organic matter in the Solar System was formed by non-aqueous processing, occurring in either the Solar nebula or in an interstellar environment. Aqueous processing on asteroids may have altered this pre-existing organic matter, but such processing did not affect in any substantial way the C = O content of the organic matter, the aliphatic C-H abundance, or the mean aliphatic chain length.

We measured trace element abundances in the individual minerals of these two angrites and compared them with the three Antarctic angrites, LEW 86010, LEW 87051 and Asuka 881371. Trace element variations in four of these meteorites (LEW 87051, Asuka 881371, Sahara 99555 and D'Orbigny) indicate rapid crystallization under near closed system conditions, consistent with their mineralogical and textural features. All four appear to be closely related and crystallized from very similar magmas. Discrepancies between their bulk REE compositions and melts calculated to be in equilibrium with the major phases may be due in part to kinetic effects of rapid crystallization. Prior crystallization of olivine and/or plagioclase may also account for the elevated parent melt composition of clinopyroxene in some of the angrites such as Asuka 881371.LEW 86010 also crystallized from a melt and represents a liquid composition, but trace element trends in clinopyroxene and olivine differ from those of the other angrites. This meteorite seems to have crystallized from a different source magma.

Ion microprobe analyses of selected trace and minor element abundances in minerals of the silicate clasts indicate that, following igneous crystallization, these clasts underwent extensive metamorphic equilibration that resulted in intra- and inter-grain redistribution of elements. There is also evidence in the elemental microdistributions that these clasts were subsequently affected to varying degrees by alteration resulting from redox reactions involving the indigenous silicates and externally derived reducing agents (such as phosphorus, derived from the mesosiderite metal) at the time of metal-silicate mixing. Furthermore, our results suggest that the varying degrees of alteration by redox reactions recorded in the different clasts were most likely facilitated by different degrees of remelting induced by heating during the metal-silicate mixing event. After taking into account the effects of these postmagmatic secondary processes, comparison of the trace and minor element concentrations and distributions in minerals of basaltic and orthopyroxenitic clasts with those of noncumulate eucrites and diogenites, respectively, suggests that the primary igneous petrogenesis, including parent magma and source compositions, of Vaca Muerta silicates were similar to those of achondritic meteorites of the Howardite-Eucrite-Diogenite (HED) association. Internal (super 53) Mn- (super 53) Cr isochrons obtained for two basaltic (pebble 16 and 4679) and two orthopyroxenitic (4659 and 4670) clasts show that chromium isotopes are equilibrated within each clast. Nevertheless, just as for noncumulate eucrites and diogenites, (super 53) Cr excesses in whole-rock samples of the basaltic clasts ( approximately 1.01 epsilon in pebble 16; approximately 1.07 epsilon in 4679) are significantly higher than in the orthopyroxene-rich clasts ( approximately 0.62 epsilon in 4659; approximately 0.53 epsilon in 4670). As in the case of the HED parent body, this suggests that Mn/Cr fractionation in the parent body of the Vaca Muerta silicate clasts occurred very early in the history of the solar system, when (super 53) Mn was still extant. However, the slope of the (super 53) Mn- (super 53) Cr isochron defined by the whole-rock samples of Vaca Muerta clasts (corresponding to a (super 53) Mn/ (super 55) Mn ratio of 3.3+ or -0.6X10 (super -6) ) is distinctly lower than that defined by the HED whole-rock samples (corresponding to a (super 53) Mn/ (super 55) Mn ratio of 4.7+ or -0.5X10 (super -6) ), indicating that the global Mn/Cr fractionation event that established mantle source reservoirs on the parent body of the Vaca Muerta silicate clasts occurred approximately 2 Ma after a similar event on the HED parent body.

A coupled three-dimensional general circulation, biogeochemical, and radiative model of the global oceans was validated using these in situ data sources and satellite data sets. Biogeochemical processes in the model were determined from the influences of circulation and turbulence dynamics, irradiance availability, and the interactions among four phytoplankton functional groups (diatoms, chlorophytes, cyanobacteria, and coccolithophores) and four nutrients (nitrate, ammonium, silica, and dissolved iron). Annual mean log-transformed dissolved iron concentrations in the model were statistically positively correlated on basin scale with observations (P<0.05) over the eight (out of 12) major oceanographic basins where data were available. The model tended to overestimate in situ observations, except in the Antarctic where a large underestimate occurred. Inadequate scavenging and excessive remineralization and/or regeneration were possible reasons for the overestimation. Basin scale model chlorophyll seasonal distributions were positively correlated with SeaWiFS chlorophyll in each of the 12 oceanographic basins (P<0.05). The global mean difference was 3.9% (model higher than SeaWiFS).The four phytoplankton groups were initialized as homogeneous and equal distributions throughout the model domain. After 26 years of simulation, they arrived at reasonable distributions throughout the global oceans: diatoms predominated high latitudes, coastal, and equatorial upwelling areas, cyanobacteria predominated the mid-ocean gyres, and chlorophytes and coccolithophores represented transitional assemblages. Seasonal patterns exhibited a range of relative responses: from a seasonal succession in the North Atlantic with coccolithophores replacing diatoms as the dominant group in mid-summer, to successional patterns with cyanobacteria replacing diatoms in mid-summer in the central North Pacific. Diatoms were associated with regions where nutrient availability was high. Cyanobacteria predominated in quiescent regions with low nutrients. While the overall patterns of phytoplankton functional group distributions exhibited broad qualitative agreement with in situ data, quantitative comparisons were mixed. Three of the four phytoplankton groups exhibited statistically significant correspondence across basins. Diatoms did not. Some basins exhibited excellent correspondence, while most showed moderate agreement, with two functional groups in agreement with data and the other two in disagreement. The results are encouraging for a first attempt at simulating functional groups in a global coupled three-dimensional model but many issues remain. Abstract Copyright (2003) Elsevier, B.V.

We evaluated the ability of treadmill exercise in a LBNP chamber to counteract bone loss in a 30-day bed rest study. Eight pairs of identical twins were randomly assigned to sedentary control or exercise groups. Exercise within LBNP decreased the bone resorption caused by bed rest and may provide a countermeasure for spaceflight. Introduction: Bone loss is one of the greatest physiological challenges for extended-duration space missions. The ability of exercise to counteract weightlessness-induced bone loss has been studied extensively, but to date, it has proven ineffective. We evaluated the effectiveness of a combination of two countermeasures--treadmill exercise while inside a lower body negative pressure (LBNP) chamber--on bone loss during a 30-day bed rest study. Materials and Methods: Eight pairs of identical twins were randomized into sedentary (SED) or exercise/LBNP (EX/LBNP) groups. Blood and urine samples were collected before, several times during, and after the 30-day bed rest period. These samples were analyzed for markers of bone and calcium metabolism. Repeated measures ANOVA was used to determine statistical significance. Because identical twins were used, both time and group were treated as repeated variables. Results: Markers of bone resorption were increased during bed rest in samples from sedentary subjects, including the collagen cross-links and serum and urinary calcium concentrations. For N-telopeptide and deoxypyridinoline, there were significant (p < 0.05) interactions between group (SED versus EX/LBNP) and phase of the study (sample collection point). Pyridinium cross-links were increased above pre-bed rest levels in both groups, but the EX/LBNP group had a smaller increase than the SED group. Markers of bone formation were unchanged by bed rest in both groups. Conclusions: These data show that this weight-bearing exercise combined with LBNP ameliorates some of the negative effects of simulated weightlessness on bone metabolism. This protocol may pave the way to counteracting bone loss during spaceflight and may provide valuable information about normal and abnormal bone physiology here on Earth.

We analyze the relationship between local and regional diversity in tropical marine communities spanning approximately 13 Myr of the Late Ordovician to test for the role of local processes in structuring local communities. We find a significant and strong positive relationship between local and regional diversity, indicating that local communities were not saturated with species and that local processes did not exert a dominant influence on local diversity. Rather, local diversity was influenced more by regional oceanographic processes that governed the size of the regional species pool. This evidence for unsaturated communities is consistent with the Walker and Valentine hierarchically structured niche model of global diversification. These results come at the beginning of the 200-Myr Paleozoic plateau in both local and global diversity and therefore raise the question whether local communities were ever saturated with species during the Paleozoic. Similar studies need to be conducted during other times in the Paleozoic to determine if this is indeed the case. JF - Paleobiology AU - Patzkowsky, ME AU - Holland, S M AD - Mark E. Patzkowsky.

This globally complete, monthly analysis of surface precipitation at 2.5 degree latitude x 2.5 degree longitude resolution is available from January 1979 to the present. It is a merged analysis that incorporates precipitation estimates from low-orbit satellite microwave data, geosynchronous-orbit satellite infrared data, and surface rain gauge observations. The merging approach utilizes the higher accuracy of the low-orbit microwave observations to calibrate, or adjust, the more frequent geosynchronous infrared observations. The dataset is extended back into the premicrowave era (before mid-1987) by using infrared-only observations calibrated to the microwave-based analysis of the later years. The combined satellite-based product is adjusted by the rain gauge analysis. The dataset archive also contains the individual input fields, a combined satellite estimate, and error estimates for each field. This monthly analysis is the foundation for the GPCP suite of products, including those at finer temporal resolution. The 23-yr GPCP climatology is characterized, along with time and space variations of precipitation.

Part II: Validation AN - 18037144; 5775808 AB - Top-of-atmosphere (TOA) radiative fluxes from the Clouds and the Earth's Radiant Energy System (CERES) are estimated from empirical angular distribution models (ADMs) that convert instantaneous radiance measurements to TOA fluxes. This paper evaluates the accuracy of CERES TOA fluxes obtained from a new set of ADMs developed for the CERES instrument onboard the Tropical Rainfall Measuring Mission (TRMM). The uncertainty in regional monthly mean reflected shortwave (SW) and emitted longwave (LW) TOA fluxes is less than 0.5 W m-2, based on comparisons with TOA fluxes evaluated by direct integration of the measured radiances. When stratified by viewing geometry, TOA fluxes from different angles are consistent to within 2% in the SW and 0.7% (or 2 W m-2) in the LW. In contrast, TOA fluxes based on ADMs from the Earth Radiation Budget Experiment (ERBE) applied to the same CERES radiance measurements show a 10% relative increase with viewing zenith angle in the SW and a 3.5% (9 W m-2) decrease with viewing zenith angle in the LW. Based on multiangle CERES radiance measurements, 1 degree regional instantaneous TOA flux errors from the new CERES ADMs are estimated to be <10 W m-2 in the SW and <3.5 W m-2 in the LW. The errors show little or no dependence on cloud phase, cloud optical depth, and cloud infrared emissivity. An analysis of cloud radiative forcing (CRF) sensitivity to differences between ERBE and CERES TRMM ADMs, scene identification, and directional models of albedo as a function of solar zenith angle shows that ADM and clear-sky scene identification differences can lead to an 8 W m-2 root-mean-square (rms) difference in 1 degree daily mean SW CRF and a 4 W m-2 rms difference in LW CRF. In contrast, monthly mean SW and LW CRF differences reach 3 W m-2. CRF is found to be relatively insensitive to differences between the ERBE and CERES TRMM directional models.

The relative importance of various contributing factors is investigated in this paper through the use of Goddard Earth Observing System (GEOS) GCM simulations. Seven different experiments, each containing an ensemble of four simulations, were conducted with the GCM. For each experiment, the GCM was integrated through the summers of 1987 and 1988 starting from an analyzed atmosphere in early January of each year. In the baseline case, only the SST anomalies and climatological vegetation parameters were prescribed, while everything else (such as soil moisture, snow cover, and clouds) was interactive. The precipitation differences (1988 minus 1987) show that the GCM was successful in simulating reduced precipitation in 1988, but the accompanying low-level circulation anomalies in the Midwest were not well simulated. To isolate the influence of the model's climate drift, analyzed winds and analyzed soil moisture were prescribed globally as continuous updates (in isolation or jointly). The results show that remotely advected wind biases (emanating from potential errors in the model's dynamics and physics) are the primary cause of circulation biases over North America. Inclusion of soil moisture helps to improve the simulation as well as to reaffirm the strong feedback between soil moisture and precipitation. In a case with both updated winds and soil moisture, the model produces more realistic evapotranspiration and precipitation differences. An additional case also used soil moisture and winds updates, but only outside North America. Its simulation is very similar to that of the case with globally updated winds and soil moisture, which suggests that North American simulation errors originate largely outside the region. Two additional cases examining the influence of vegetation were built on this case using correct and opposite-year vegetation. The model did not produce a discernible improvement in response to vegetation for the drought year. One may conclude that the soil moisture governs the outcome of the land-atmosphere feedback interaction far more than the vegetation parameters. A primary inference of this study is that even though SSTs have some influence on the drought, model biases strongly influence the prediction errors. It must be emphasized that the results from this study are dependent upon the GEOS model's identified errors and biases, and that the conclusions do not necessarily apply to results from other models.

The effects of passing vehicles on the foraging behavior of wading birds was studied using observational and experimental methods at the Merritt Island National Wildlife Refuge near Titusville, Florida. Foraging wading birds were more likely to be disturbed when vehicles slowed or stopped adjacent to them, than when vehicles continued driving by. In an area with a high rate of human visitation, some individual wading birds responded more strongly to passing vehicles than did others, suggesting that some were habituated to disturbance. Experimental disturbance by a vehicle caused a significant depression in the foraging rates of the Snowy Egret (Egretta thula) and the Great Egret (Ardea alba) and non-significant reductions in foraging rates in the Tricolored Heron (E. tricolor). Nineteen percent of the birds flushed following disturbance. The proximity of the disturbance vehicle influenced the probability of flushing in a species-specific manner with the Tricolored Heron being the most sensitive, the Great Egret intermediate, and the Snowy Egret the least sensitive. Recommendations to managers include concentrating ecotourism in certain areas and educating ecotourists about the effects of their behavior on wading birds.

Six different SCMs were used to simulate ACE-2 case studies of clean and polluted cloudy boundary layers, with the objective being to identify limitations of the aerosol/cloud/radiation interaction schemes within the range of uncertainty in in situ, reanalysis and satellite retrieved data. The exercise proceeds in three steps. First, SCMs are configured with the same fine vertical resolution as the ACE-2 in situ data base to evaluate the numerical schemes for prediction of aerosol activation, radiative transfer and precipitation formation. Second, the same test is performed at the coarser vertical resolution of GCMs to evaluate its impact on the performance of the parameterizations. Finally, SCMs are run for a 24-48 hr period to examine predictions of boundary layer clouds when initialized with large-scale meteorological fields. Several schemes were tested for the prediction of cloud droplet number concentration (N). Physically based activation schemes using vertical velocity show noticeable discrepancies compared to empirical schemes due to biases in the diagnosed cloud base vertical velocity. Prognostic schemes exhibit a larger variability than the diagnostic ones, due to a coupling between aerosol activation and drizzle scavenging in the calculation of N. When SCMs are initialized at a fine vertical resolution with locally observed vertical profiles of liquid water, predicted optical properties are comparable to observations. Predictions however degrade at coarser vertical resolution and are more sensitive to the mean liquid water path than to its spatial heterogeneity. Predicted precipitation fluxes are severely underestimated and improve when accounting for sub-grid liquid water variability. Results from the 24-48 hr runs suggest that most models have problems in simulating boundary layer cloud morphology, since the large-scale initialization fields do not accurately reproduce observed meteorological conditions. As a result, models significantly overestimate optical properties. Improved cloud morphologies were obtained for models with subgrid inversions and subgrid cloud thickness schemes. This may be a result of representing subgrid scale effects though we do not rule out the possibility that better large-forcing data may also improve cloud morphology predictions.

Congo AN - 16173042; 5801966 AB - Nyamuragira (Virunga chain, D.R. Congo) is among Africa's most active volcanoes, but direct observations of its eruptions are rare. From 1978-2002 the Total Ozone Mapping Spectrometer (TOMS) instruments measured SO sub(2) emissions during each of Nyamuragira's 13 most recent eruptions. Due to continuous co- eruptive SO sub(2) degassing, estimating the total atmospheric SO sub(2) loading resulting from eruptions of Nyamuragira is not straightforward. Using TOMS SO sub(2) plume cross-sections and model wind profiles we derive eruptive SO sub(2) fluxes and SO sub(2) loss rates for emissions on 19 October 1998 and 6 February 2001, giving peak SO sub(2) fluxes of 0.21 and 0.74 Tg day super(-1) respectively and loss rates of similar to 10 super(-6)-10 super(-5) s super(-1). Based on current data, time-averaged SO sub(2) emission rates at Nyamuragira are comparable to persistent emitters (Etna, Kilauea), but eruptive fluxes at Nyamuragira are much higher. Considering the alkaline composition of Virunga lavas, eruptive CO sub(2) fluxes could be seven times the SO sub(2) flux.

These meteorites also indicate that the mantle source regions of this volcanism are modestly to extremely depleted by terrestrial standards. These 2 observations produce a conundrum. How is it that such depleted source regions have produced basaltic magma for such a long time? This contribution attempts to quantify the radiogenic heat production in 2 distinct martian mantle source regions: those of the shergottites and nakhlites. Compared to the depleted upper mantle of the Earth (MORB), the nakhlite source region is depleted by about a factor of 2, and the shergottite source region is depleted by a factor of 6. According to current geophysical models, the nakhlite source contains the minimum amount of radioactive heat production to sustain whole-mantle convection and basalt generation over geologic time. A corollary of this conclusion is that the shergottite source contains much too little radioactivity to produce recent (<200 Ma) basalts. A model martian interior with a deep nakhlite mantle that is insulated by a shallow shergottite mantle may allow basalt production from both source regions if the divide between the nakhlite-shergottite mantles acts as a thermal boundary layer. Similarities between lunar and martian isotopic reservoirs indicate that the Moon and Mars may have experienced similar styles of differentiation JF - Meteoritics & Planetary Science AU - Jones, J H AU - Treiman, Allan H Y1 - 2003/12// PY - 2003 DA - December 2003 SP - 1807 EP - 1814 PB - Meteoritical Society, Fayetteville, AR VL - 38 IS - 12 SN - 1086-9379, 1086-9379 KW - nakhlite KW - volcanic rocks KW - stony meteorites KW - isotopes KW - radioactivity KW - Martian meteorites KW - igneous rocks KW - mantle KW - Mars KW - SNC Meteorites KW - meteorites KW - volcanism KW - heat flow KW - basalts KW - rare earths KW - geochemistry KW - QUE 94201 KW - convection KW - achondrites KW - boundary conditions KW - terrestrial planets KW - planets KW - Antarctica KW - shergottite KW - metals KW - heat sources KW - Queen Alexandra Range Meteorites KW - planetary interiors KW - Nd-143/Nd-142 KW - theoretical models KW - terrestrial comparison KW - neodymium KW - 05B:Petrology of meteorites and tektites KW - 04:Extraterrestrial geology UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/1447100866?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/ProQ%3Ageorefmodule&rft_val_fmt=info:ofi/fmt:kev:mtx:journal&rft.genre=article&rft.jtitle=Meteoritics+%26+Planetary+Science&rft.atitle=Constraints+on+the+structure+of+the+Martian+interior+determined+from+the+chemical+and+isotopic+systematics+of+SNC+Meteorites&rft.au=Jones%2C+J+H%3BTreiman%2C+Allan+H&rft.aulast=Jones&rft.aufirst=J&rft.date=2003-12-01&rft.volume=38&rft.issue=12&rft.spage=1807&rft.isbn=&rft.btitle=&rft.title=Meteoritics+%26+Planetary+Science&rft.issn=10869379&rft_id=info:doi/10.1111%2Fj.1945-5100.2003.tb00016.x L2 - http://cavern.uark.edu/~meteor/ LA - English DB - GeoRef N1 - Conference title - Workshop on Unmixing the SNCs; chemical, isotopic, and petrologic components of the Martian meteorites N1 - Copyright - GeoRef, Copyright 2013, American Geosciences Institute.

AN - 71496469; 14703908 AB - Our ecological footprint analyses of coral reef fish fisheries and, in particular, the live reef fish food trade (FT), indicate many countries' current consumption exceeds estimated sustainable per capita global, regional and local coral reef production levels. Hong Kong appropriates 25% of SE Asia's annual reef fish production of 135 260-286 560 tonnes (t) through its FT demand, exceeding regional biocapacity by 8.3 times; reef fish fisheries demand out-paces sustainable production in the Indo-Pacific and SE Asia by 2.5 and 6 times. In contrast, most Pacific islands live within their own reef fisheries means with local demand at < 20% of total capacity in Oceania. The FT annually requisitions up to 40% of SE Asia's estimated reef fish and virtually all of its estimated grouper yields. Our results underscore the unsustainable nature of the FT and the urgent need for regional management and conservation of coral reef fisheries in the Indo-Pacific.

AN - 62164513; ED482160 AB - The High School Sophomore Cohort of 1980 followed nine different pathways to a 4-year college degree. These paths were formed by a combination of different levels of academic preparation secured in high school and the first type of postsecondary institution attended. The pathway most likely to lead to a 4-year degree is one defined by acquiring high academic resources in high school and entering at a 4-year institution on high school completion. Those who followed this path had a 78% chance of graduating within 11 years. Highest-socioeconomic status (SES) students followed this pathway, resulting in an 81% graduation rate. Not all paths are equally available to all SES groups. Lowest-SES students journeyed on a pathway defined by moderate academic resources and first enrollment in a 2-year institution. Only 3.3% of these students earned a 4-year degree. A 44% SES-based degree completion gap separating lowest-SES students from highest-SES students found using simple descriptive statistics is reduced to 24% when myriad factors are considered simultaneously.

The NASA-CASA model was driven by vegetation properties derived from the Advanced Very High Resolution Radiometer (AVHRR) and radiative transfer algorithms that were developed for Moderate Resolution Imaging Spectroradiometer (MODIS). For the terrestrial biosphere, predicted net ecosystem production (NEP) flux for atmospheric CO (sub 2) has varied widely between an annual source of -0.9 Pg C per year and a sink of +2.1 Pg C per year. The southern hemisphere tropical zones (SHT, between 0 degrees and 30 degrees S) have a major influence over the predicted global trends in interannual variability of NEP. In contrast, the terrestrial NEP sink for atmospheric CO (sub 2) on the North American (NA) continent has been fairly consistent between +0.2 and +0.3 Pg C per year, except during relatively cool annual periods when continental NEP fluxes are predicted to total to nearly zero. The predicted NEP sink for atmospheric CO (sub 2) over Eurasia (EA) increased notably in the late 1980s and has been fairly consistent between +0.3 and +0.55 Pg C per year since 1988. High correlations can be detected between the El Nino Southern Oscillation (ENSO) and predicted NEP fluxes on the EA continent and for the SHT latitude zones, whereas NEP fluxes for the North American continent as a whole do not correlate strongly with ENSO events over the same time series since 1982. These observations support the hypothesis that regional climate warming has had notable but relatively small-scale impacts on high latitude ecosystem (tundra and boreal) sinks for atmospheric CO (sub 2) .

And what is the best approach for NASA, in partnership with other agencies, to address those challenges? A new report, Living on a Restless Planet, provides a blueprint for answering these questions. The top priority for a new spacecraft mission in the area of solid Earth science over the next 5 years, according to this report, is a satellite dedicated to Interferometric Synthetic Aperture Radar (InSAR). At the request of NASA, the Solid Earth Science Working Group (SESWG) developed a strategy for the highest priority objectives in solid Earth science for the space agency over the next 25 years. The strategy addresses six challenges that are of fundamental scientific importance, have strong implications for society, and are amenable to substantial progress through a concerted series of scientific observations from space.

Textural, mineral compositional, and bulk compositional evidence show that EET 99402 and EET 99407 are paired. ALH 84025, EET 99402, and EET 99407 have igneous textures. Petrofabric analyses of ALH 84025 and EET 99407 demonstrate the presence of lineations and probable foliations of olivine grains that support formation as igneous cumulates. Mineral minor element chemistry and bulk rock incompatible lithophile element contents of the brachinites are distinct from those of acapulcoite-lodranite clan meteorites, a suite of high-grade metamorphic rocks and anatectic residues. The differences demonstrate a higher blocking temperature of equilibration for the brachinites and that cumulus plagioclase is present in EET 99402, EET 99407, and probably ALH 84025, thus indicating an igneous origin. Brachinites are differentiated, ultramafic achondrites, and are not part of a suite of primitive achondrites. We infer that their parent asteroid is a differentiated body. Brachina has an excess of (super 129) Xe correlated with reactor-produced (super 128) Xe, demonstrating that short-lived (super 129) I was present at the time of formation. This, plus literature data, attests to early formation of the brachinites, within a few Ma of the formation of chondrites. Ar-Ar age data show that Brachina and EET 99407 were degassed about 4.13 Ga ago, possibly by a common impact event. EET 99402 and EET 99407 show petrographic evidence for shock, including possible conversion of plagioclase to maskelynite followed by devitrification. Brachina is unshocked, making a direct association between the Ar-Ar age and textures ambiguous.

Warm-minus-cold composites of the ensemble mean and observed tropical Pacific precipitation, averaged for the three warmest El Nino and three coldest La Nina winters, show large positive anomalies near the date line that extend eastward to the South American coast. The same is true for composites of the spring following the event. In the composites of the autumn preceding the event, the precipitation is weaker and shifted off the equator in the far eastern Pacific, where equatorial SSTs are too low to support convection. The corresponding boreal winter 200-hPa height composites show strong signals in the Tropics and midlatitudes of both hemispheres. The subsequent spring composites are similar, but weaker in the northern extratropics. In the preceding autumn composites, the overall height signal is quite weak, except in the southern Pacific. The model dependence of the signal (variance of ensemble means) and noise (variance about the ensemble means) of the seasonal mean 200-hPa height is small, a result that holds for all three seasons and is in contrast to earlier studies. The signal-to-noise ratio is significantly greater than unity in the Tropics (all seasons), the northern Pacific and continental North America subtropics (boreal winter and spring), and the southern Pacific subtropics (boreal autumn). Rotated empirical orthogonal function analysis of the tropical Pacific SST recovers El Nino-like dominant patterns in boreal winter and spring, but emphasizes two SST patterns in autumn, one with largest SST in the far eastern tropical Pacific and one with a maximum nearer the date line. Two methods are used to assess the precipitation and height field responses to these patterns: linear regression of the ensemble means on the principal component (PC) time series of SST and identification of patterns that optimize the signal-to-noise ratio. The two methods yield remarkably similar results. The optimal height patterns for boreal winter and spring are similar, although the spring response over the northern extratropics is somewhat weaker, and some subtle changes in phase are found in all three GCMs. The associated optimal time series have serial correlations with the leading PC of SST that exceed 0.9 for all GCMs for winter and spring. For autumn the time series of the leading two optimal patterns each has a serial correlation with the corresponding PC of SST that exceeds 0.7 for the COLA and NSIPP GCMs. The autumn 200-hPa-height leading optimal pattern (response to eastern Pacific SST) is quite weak, representing nearly uniform tropical warming. The second optimal pattern (response to central Pacific SST) shows a robust wave train in the southern Pacific, with a consistent belt of low height over northern midlatitudes.

Changes over time in 13C/12C values of these reservoirs indicate changes both in isotopic discrimination during biosynthesis and processing of organics, and in relative rates of burial of organics vs carbonates. The range in 13C/12C values of kerogens older than 2.1 Ga exceeds that of younger kerogens. Anaerobic microbes assimilate CO2 by a variety of pathways that differ substantially in isotopic discrimination. The decrease over time in the range of kerogen 13C/12C perhaps reflects the transition from a world where global primary production (GPP) was dominated by diverse anaerobes to a world where cyanobacteria and algae dominated. The onset after 2.3 Ga of major isotopic excursions for carbonates indicates large episodic burial events of organic carbon and shows that oxygenic photosynthesis was globally significant. Increases in the range of 34S/35S of sulfides largely coincide with these organic burial events and are consistent with rising seawater sulfate levels. The rise of O2 photosynthesis increased GPP by 100-fold or more. Fermentation of those abundant photosynthetic organics produced hydrogen that, in an anoxic world, increased the rate of H2 escape to space and hastened the oxidation of the global environment. Evidence for the existence of O2 photosynthesis at 3.5 Ga is NOT compelling. We are challenged to discover the oldest evidence of its existence, when it ascended to global dominance, and how the ascent affected reservoirs of Fe3+, sulfate, nitrate and O2. The products of O2 photosynthesis can be actively and almost completely recycled within modern microbial mats, with little or no net effect upon the external environment. Ecological studies of such mats can offer clues about an ancient anoxic world having "oases" of O2 photosynthetic communities.

These models will be used in instructional settings to help students gain a better understanding of topics related to comparative geology, geomorphology and topography. The models are innovative in that they will provide students with a tactile representation of the three-dimensional character of a planetary surface, which is often difficult to visualize from 2-dimensional maps. Along with the models, associated lesson plans are being designed to help students and teachers understand topics related to topography such as scale, shape, landform evolution, contour, slope, and exaggeration. Several model kits based on specific science themes will be produced over the next year. Initial models and lessons are focusing on model pairs of similar features on Earth and Mars including: large volcanoes, canyons and polar ice caps. Each of these kits will include: relevant 3-dimensional models, descriptive text, 2-dimensional maps and images, lessons and suggested classroom activities that are aligned with the National Science Education Standards (NSES) and Benchmarks. For initial testing the kits will be evaluated by a group of middle school science teachers who are taking masters level course work in the Masters of Science in Education Program at Johns Hopkins University. These teachers will test these kits in the classroom and provide feedback and suggestions for improvement. To reach a broader community, web based versions of the kits are also being planed. In lieu of the actual 3-dimensional plastic models these web sites will use interactive topography data visualization tools using QuickTime virtual reality or Macromedia Flash technology that will allow students to rotate and view the geologic features from many angles. Web based interactive visualizations and exercises dealing with other common topography measurement parameters such as slope, contouring and vertical exaggeration will also be produced. These web based exercises can be used independently or as a supplement to the plastic model kits.

The Image Composite Editor (ICE) (http://earthobservatory.nasa.gov/Laboratory/ICE/ice_intro.html) provides a simple web-based interface for students and other non-expert users to compare and contrast multiple datasets. ICE enables simple mathematical analysis, animation, band compositing, data querying, and graphing with up to three datasets. ICE is capable of utilizing both image data (radiances) and derived data (geophysical parameters). ICE is designed for ease-of-use, rather than comprehensive data analysis features. Current lessons include comparisons of biological and physical properties of the ocean surrounding the Channel Islands, El Nino, forest fires, seasonal change, and interannual variability. Each example uses remote sensing data to illustrate natural processes and the relationships between different geophysical parameters (for example, the influence of sea surface temperature on biological productivity in the ocean). ICE relies on 8-bit raster images (such as GIFs) and html so additional datasets can be easily added.

Currently favored mechanisms center on the presence of widespread oceanic anoxia, perhaps triggered by greenhouse warming induced by Siberian trap volcanism. The spread of anoxic waters onto continental shelves restricted the available habitat for aerobic organisms, and upwelling of sulfidic and CO (sub 2) -rich deepwaters may have induced hypercapnia in planktonic organisms. However, we find mass extinction on land to be an unlikely consequence of carbon dioxide levels equilibrated with the ocean at 2000 ppmv, only 7 times the preindustrial level. We thus propose a modification of the anoxia mechanism, one that considers the possibility that the chemocline separating anoxic, sulfidic deep waters from the atmosphere, originally at the base of the wind-mixed layer of the ocean, collapsed catastrophically to the surface as sulfide levels built up in the deep ocean, especially if Late Permian oxygen levels were significantly lower than today's. We calculate the conditions under which such a collapse would occur, and the consequences for the resultant flux of H (sub 2) S to the atmosphere. Widespread outcropping of sulfidic waters creates a flux to the atmosphere that quickly depletes the troposphere of hydroxyl radical, thereby allowing a hydrogen-sulfide rich plume to waft across the continents. In the Permian, such a cloud would poison terrestrial organisms in the way that aqueous H (sub 2) S had already caused the demise of marine organisms. Biomarker data from Permian deep-sea sediments from Japan are evaluated in light of the predicted burst of productivity of photoautotrophic sulfur bacteria.

A sequence of thin-bedded shales, quartzite and feldspathic sandstone was traced into the folded mountain range. The flat-lying sediments of the basin are deformed into open folds in the foothills of the mountains and finally overturned folds and thrusts exposing increasingly lower parts of the section towards the east. The region exhibits classic relations, on a small scale, of a typical foreland basin and orogenic belt. The tectonic setting and age is part of the Pan-African orogeny associated with plate collisions that formed Gondwanaland. The Ghana experience provided an important lesson in the importance of knowing the stratigraphy of a region in order to unravel its structure. The author went on to apply methods of classical stratigraphy to planetary geologic mapping and understanding the geologic evolution of the Moon, Venus and Mars. The Peace Corps experience was vital to this geologist's professional development as a planetary scientist.

[1]. These are interpreted as secondary minerals formed at low temperature [2,3] in an aqueous medium [4,5]. Dispersed within these carbonates are nm-sized, single crystal magnetites. Using a combination of classical and tomographic transmission electron microscopy we have been able to demonstrate that a fraction of these magnetites has chemical and physical properties nearly identical to intracellular magnetite crystals produced by magnetotactic bacteria strain MV-1 [6-8]. The MV-1 magnetite morphology has been described as truncated hexaoctahedral [9] and appears to be tightly regulated by the bacteria cell under genetic control. In the natural terrestrial environment, such truncated hexaoctahedral magnetite appears only to been produced through biogenic mediation [6 and refs. therein]. To date, no credible synthetic inorganic procedure has been able to reproduce magnetite with this morphology. Nor might it be expected, since the truncated hexaoctahedron possesses hexagonal symmetry, whereas the underlying crystal symmetry of the magnetite unit cell is itself cubic. A posteriori, we suggest those ALH84001 magnetites with truncated hexaoctahedral geometry, indistinguishable from MV-1 magnetite, were mediated by similar biogenic processes on early Mars.

To ascertain intraplate activity, one must aggregate all tectonic data into one coherent digital architecture. The best scientific visualization tool for this is a Geographic Information System (GIS). Such a visualization tool has already been developed (Yates, et. al, 1998; and Lowman, et., al, 1999) to quantify global tectonic activity for the last one million years. This tectonic atlas is the Digital Tectonic Activity Map (DTAM). The DTAM depicts tectonic activity for the past one million years at a length scale of 9-km. The DTAM project has embarked on a study to quantify intraplate tectonic parameters for the proposed Global Earthquake Satellite System (GESS). This study is focusing on determining the spatial extent from plate boundary tectonics through a transitional zone, to the intraplate tectonics of the continental craton. The plate boundary sites chosen are the NUVEL-1 locations (DeMets, et. al., 1990). These provide a common reference frame from the mid-oceanic ridge system. This has been done for each of the four primary study sites: (1) Aegean Archipelago, (2) Australia, (3) Central and Southern India, and the (4) St. Lawrence River. By ascertaining the tectonic activity of each study region, one may correlate the tectonic activity with other similar geological provinces. By spatially contouring the seismic epicenter distributions for each of the study sites, regions of active or increased intraplate tectonics can be identified.

The architecture of the upper plate includes a well developed fold and thrust belt in the outer part of the forearc above the locked zone (Albatross Banks-Kodiak Shelf fault zones), a mid-forearc high above the transition zone (Kodiak Archipelago), and a large forearc basin adjacent to the arc (Shelikof Strait). Late Quaternary uplift of the Kodiak Islands has resulted in the formation of a widespread raised coastal terrace interpreted to have been cut during oxygen isotope stage 5e (133-120 ka). The elevation of the terrace increases gradually from about 15 m on the northwest side to about 40 m on the southeast side of the islands, reflecting long term uplift rates of about 0.15 mm/yr (west side) to 0.3 mm/yr (east side). However, at Narrow Cape, located near the zero isobase of the 1964 earthquake, the elevation of the terrace increases abruptly to approximately 280 m. Narrow Cape is traversed by at least four active faults (post-glacial, approximately 14 ka) including the Narrow Cape fault, one of principal structures in the arc-side margin of the fold and thrust belt. At the Cape the late Pleistocene coastal terrace is displaced by the Narrow Cape fault vertically approximately 180 m (vertical slip rate approximately 1.5 mm/yr) and post-glacial fluvial channels crossing the fault are offset left laterally as much as 30 m (horizontal slip rate approximately 2 mm/yr). Trenches across post-glacial scarps on the Claudia, Bison, and Bear Paw faults at the Cape show at least four post-glacial episodes of high angle left lateral and left normal oblique slip, the most recent less than about 3 ka. Holocene slip rates for these faults derived from offset tephras and soils exposed in the trenches range from approximately 0.03 to approximately 0.1 mm/yr. We interpret the faulting at the Cape to reflect deformation at a large releasing stepover on the Narrow Cape fault. The Narrow Cape fault and nearby Kodiak Island fault are major active predominately strike slip structures in the arc-side margin of the fold and thrust belt. These faults appear to accommodate much of the lateral component of subduction and constitute sources of large strike-slip earthquakes in the forearc.

Earlier studies of this region using MOLA data identified numerous new volcanic features. A majority of these features were not able to be resolved in pre-MOLA image data (primarily Viking Mission data) because this region is difficult to image due to the presence of dust and frost and because these features have gentle slopes. Using the high-resolution MOLA data, we measured parameters such as basal diameter and area, edifice and cavity volume, flank slope, and crater dimensions. Using these data we were able to identify several types of topographic landforms. Each landform type tends to cluster spatially within the study area. Some of the volcanic features in the polar region appear to be similar to those of lava shields common in more equatorial latitudes of Mars. However, consistent with earlier studies, the flank slopes tend to be slightly steeper and the summit craters larger at higher latitudes. Also, in the North Polar Region, we identified types of volcanic features that are relatively uncommon or even unseen in more southerly latitudes. These features resemble more explosive terrestrial features such as cinder cones, tuff cones, and other landforms indicative of volatile-rich lava interactions. We found that in images it is difficult to differentiate between polar volcanic cones and polar impact craters that appear to have been filled and exhumed. Therefore, we developed a preliminary method using topographic signatures to differentiate between these visually similar landforms. Topographic data suggest that the cavity volume normalized by the edifice volume is typically an order of magnitude or more larger for the impact craters than for the volcanic cones. Also, the width of the flanks tends to be greater for volcanic cones than for similar-diameter impact craters. In addition, topographic data were used to differentiate between volcanic cones and fresh impact craters. This differentiation used the relationship between the edifice volume to diameter ratio and the flank slope.

BC results from the incomplete combustion of fossil fuels (for example, coal and petroleum) and biomass (for example, vegetation burned in forest fires and slash-and-burn agriculture). The impetus for studying the environmental cycling of BC results from its importance as (1) a "sink" for atmospheric carbon, (2) a tracer for recent and historical combustion processes, (3) a mediator of the Earth's radiative heat balance, and (4) a carrier of inorganic and organic pollutants. BC abundance and isotopic signatures in suspended and surface sediments from the coastal zones of three watersheds in the U.S. were quantified in this study. The three watersheds studied were (1) the Eel River, (2) the Mississippi/Atchafalaya Rivers, and (3) the Chesapeake Bay estuary. These three watersheds, if taken together, are responsible for a significant portion of carbon fluxes from the continental U.S. to the oceans. Sediments were extracted for BC using a hydrofluoric acid demineralization-potassium dichromate oxidation procedure. At all sites in this study, the BC extraction procedure yielded a lower total % mass recovery in fluvial suspended sediments in contrast to coastal surface sediments, possibly implicating aerosol rather than fluvial transport and deposition, as a relatively greater contributor of sedimentary BC to offshore regions. In this study, carbon stable isotope ratios and natural abundances of radiocarbon were used to delineate sources of BC. Whereas, isotopic analyses of BC for all sites are currently being completed, preliminary radiocarbon abundances from the Mississippi River/Atchafalya River watershed (draining 41% of the U.S.), suggest a predominance of age depleted and possibly fossil-fuel derived BC from that watershed. Ongoing analyses of the Eel River and Chesapeake Bay will complete this snapshot assessment of BC flux from the U.S. into the surrounding coastal oceans.

Use of compound specific isotope analysis adds additional refinement to taxonomic attribution and provides information related to carbon cycling within a mat community. Our study focuses on lipid biomarkers associated with a Microcoleus-microbial mat found in hypersaline ponds at Guerrero Negro, Baja California Sur. Specific biomarkers for diatoms, cyanobacteria, archaea, green nonsulfur (GNS), sulfur oxidizing, sulfate reducing, and methanotrophic bacteria have been identified. Analyses of the ester-bound fatty acids indicated a highly diverse bacterial community. The low abundance of ether-bound isoprenyl lipids suggests a relatively small archaeal population. The delta (super 13) C for cyanobacterial biomarkers such as the monomethylalkanes (-26.0 to -27.6%) and hopanoids (-16.8%) was consistent with cyanobacterial biomass in the -15 to -22% range, considerably lighter than bulk mat at -10.5%. A variety of C (sub 28) to C (sub 34) wax esters (WXE), a biomarker for GNS bacteria, were most abundant in an anaerobic zone just below Microcoleus. WXE abundance in the upper mat layers ( approximately 400 ng mg (super -1) TOC) suggests a relatively small GNS population. A mass weighted delta (super 13) C value of -17.0% for WXE relative to the delta (super 13) C (sub DIC) of -5 to -8% obtained for these ponds was generally consistent with incorporation of bicarbonate via the 3-hydroxypropionate pathway and supports previous evidence for photoautotrophic growth of marine GNS. A C30:1 squalane, a biomarker associated with hypersalinity, was the most abundant archaeal lipid recovered and the most enriched biomarker identified (-7.0 to -10.8%). The delta (super 13) C for potential methanogen biomarkers, sn-2-hydroxyarchaeol and tetraether dibiphytanes, were relatively heavy in the -11 to -16 % range relative to associate CH (sub 4) values which approached -60%.

The interpretation of lithospheric magnetic anomalies is inherently non-unique and complimentary magnetic petrology information is essential for developing global magnetic models. A Global Magnetic Petrology Database (MPDB) is now being compiled at NASA/Goddard Space Flight Center and consists of many thousands of records. The purpose of this database is to provide the geomagnetic community with a comprehensive and user-friendly method of accessing magnetic petrology data via Internet for a more realistic interpretation of satellite (as well as aeromagnetic and ground) magnetic anomalies. MPDB is focused on lower crustal and upper mantle rocks and includes data on mantle xenoliths, serpentinized ultramafic rocks, granulites, iron quartzites and rocks from Archean-Proterozoic metamorphic sequences from all around the world. The definition of crustal magnetic anomalies is improving due to the mini-constellation of three satellites--Oersted, Champ, and SAC-C. Recent lithospheric field models (CM3e, MF1, MF2) reveal magnetic anomalies with better resolution, for example in the areas of Iceland, Polar Urals Mountains, and Anabar Shield, where we have an excellent magnetic petrology records.

As such it provides an important testbed for the developing field of astrobiology. In addition, the Neoproterozoic provides important insights into processes and conditions that differed substantially from their present states. This presentation will review the astrobiological implications of recent discoveries and interpretations of the Neoproterozoic Earth, including those that relate to the state of the Earth-Moon system, large-scale true polar wander, global refrigeration, and accelerated evolution of the biosphere.

The lesson topics focus on landforms, comparing solar system objects, and visualizing data. These topics are core educational concepts for grades 5-8 in both The National Research Council's "National Science Education Standards" and Project 2061's "Benchmarks for Science Literacy". Following the major tenet of Universal Design for Learning (UDL), the module is designed to meet the needs of as many students as possible. The module makes use of high-resolution topographic data of Earth and Mars through the use of 3-D models, topographic contour maps and profiles. The 3-D models are an accurate representation of the three-dimensional character of a planetary surface that is often difficult for students to visualize from 2-dimensional maps. In this paper we will outline the process employed to create materials that build upon the utility of the 3-D models. The education module was created with the three principles of UDL in mind: 1) representing information in multiple formats and media; 2) providing multiple pathways for students' action and expression; and 3) providing multiple ways to engage students' interest and motivation (D. Rose & A. Meyer, 2002). The module will be initially distributed as kits that include the 3-D models and a set of lesson developed to guide students in their exploration of the topographic data and geologic processes. Future plans include the production of additional Earth-Mars comparisons such as Antarctica and the Mars north pole, and the Grand Canyon and Mars outflow channels, as well as the creation of a website that will include lesson plans, data sets and a variety of images and animations.

The three sites, Storr's Lake, San Salvador Island (Bahamas), Mono Lake (California), and the Dead Sea (Israel) represent both marine and nonmarine sites. Storr's Lake is a marine site, while the Dead Sea and Mono Lake are inland arid basins with respective elevations of 400 m below sea level, and 2100 m above sea level. Microscopically there was evidence of microbial activity at all sites, but macroscopically the sites were different. For instance, bulbous, stromatolites and thick, slimy biofilm deposits were found in Storrs Lake, Mono Lake had extensive tufa and benthic mats, but the Dead Sea lacked macroscopic signs of microbial activity. Continued deposition of microbial deposits at the three sites, and the enhanced precipitation of minerals associated with microbial fossilization will ultimately affect diagenesis and mineralogical composition of the rocks. For instance, elevated levels of Si and S identified within the Storrs Lake microbial samples, Si, Mg., Fe from Mono Lake, would not be available for recycling within the original aquatic system with the burial and subsequent lithification of fossilized microbes. Their accumulation over an extended geological period of time could indicate higher levels of these elements than were actually present in the depositional environment; hence the interpretation of the paleoenvironment may not reflect the original depositional environment.

Expanding the PSLC efforts, NASA-USGS collaboration is now focusing on topographic mapping of seismogenic zones adjacent to volcanoes in the western Cascades range in order to assess the presence of active faulting and tectonic deformation, better define the extent of lahars and understand their flow processes, and characterize landslide occurrence. Mapping of the western Rainier Zone (WRZ) was conducted by TerraPoint in late 2002, after leaf fall and before snow accumulation. The WRZ is a NNW-trending, approximately 30-km-long zone of seismicity west of Mount Rainier National Park. The Puget Lowland ALSM methods were modified to accommodate challenges posed by the steep, high relief terrain. The laser data, acquired with a density of approximately 2 pulses per sq m, was filtered to identify returns from the ground from which a bare Earth digital elevation model (DEM) was produced with a grid size of 1.8 m. The RMS elevation accuracy of the DEM in flat, unvegetated areas is approximately 10 cm based on consistency between overlapping flight swaths and comparisons to ground control points. The resulting DEM substantially improves upon Shuttle Radar Topography Mission and USGS photogrammetric mapping. For example, the DEM defines the size and spatial distribution of flood erratics left by the Electron lahar and of megaclasts within the Round Pass lahar, important for characterizing the lahar hydraulics.

The image was combined with the: a) Digital Elevation Model, b) Canadian and Maine digital geologic maps, c) heat flow data, d) seismicity data, e) World Stress Map (WSM) stress vectors and f) Global Positioning System data into an Object-Oriented Geographical Information System (GIS). The result produced a new and integrated view, including the geomorphology, of the region straddling the St. Lawrence River valley from Mt. Katahdin in Maine to Quebec and Ottawa in Canada. Earthquake epicenters are highly correlated with areas of high heat flow and the trend of the St. Lawrence River valley. The seismic activity of the area offers a distinctive vantage for understanding crustal dynamics in an intra-plate region because of its spatial distribution along the zones of weakness in the crust. The rift zone is under apparent brittle failure which is manifested by the increasing earthquakes in terms of magnitude and quantity. There are two regional aggregations of seismic epicenters along the St. Lawrence River. Regional Aggregate-1 is from 47-48oN along the river, while Regional Aggregate-2 from 49-50oN. By quantifying tectonic activity in terms of seismic activity, satellite imagery, heat flow, and structural elements a more comprehensive evaluation of the regional tectonics may be ascertained.

Originally this program was designed for educational outreach activities for middle schools. Recently, ISS-EarthKAM has observed environmental, geomorphic, and land-use/land-cover change processes for scientists studying earth system science. An example of such change-detection monitoring have been of Mediterranean Islands that are important for issues of anthropogenic activities, climate change, and island biogeographic effects. Regular monitoring of oceanic islands has allowed researchers to monitor selected islands index study sites for changing aspects of slopes (Garvin, et al., 2002). Therefore, by observing inter-annual variability, slope-aspects, and varying sun-angles, a more quantitative assessment of surface features can be ascertained (Soulakellis, et al., 2003). This imagery has allowed researchers to focus on particular islands (i.e., Aegean Archipelago) for further geographic and geomorphic analysis pertaining to climate change. This type of study may act as a key example of utilizing readily available imagery derived from the ISS, for the researcher in science activities pertaining to global monitoring of the Earth's biosphere.

The recognition of uncultured Archaea (ANME-1 and ANME-2), phylogenetically related to methanogens, as mediators of this globally important process has recently been established by coupled isotopic and molecular surveys of lipid biomarkers, 16S rRNA genes, and fluorescent in situ hybridization. In this study, we examined the diversity of Archaea and sulfate-reducing bacteria involved in AOM within methane seep sediments of the Eel River basin using directly coupled isotopic and phylogenetic analyses at the level of individual microorganisms. The combined application of secondary ion mass spectrometry and fluorescent in situ hybridization (FISH-SIMS) revealed extreme carbon-13 depletion (down to -96ppm) in the biomass of the ANME-1 and ANME-2 cells, providing direct evidence of methane assimilation by both archaeal groups within anoxic seep sediments. Members of the ANME-2 and/or ANME-1 were abundant in methane-laden sediments underlying dense chemosynthetic clam beds, sulfide-oxidizing microbial mats, and bubbling vents. Both groups formed physical associations with Bacteria including, but not limited to, the sulfate-reducing Desulfosarcina/Desulfococcus. In contrast to the tight syntrophic association observed between the ANME-2 and the Desulfosarcina group, the carbon-13 depleted ANME-1 archaea were frequently found without a bacterial partner, suggesting that this group may be capable of oxidizing methane autonomously by a currently unrecognized mechanism. Additionally, stable carbon isotope values for select microorganisms, not thought to be involved in AOM (e.g., Beggiatoa-like filamentous bacteria), also contained traces of methane carbon in their biomass. This indicates the potential for ecosystem-wide incorporation of methane-derived substrates by the greater microbial methane seep community. The results from these coupled fine-scale isotopic and phylogenetic analyses illustrate the complexity of the microbial communities and interactions within the seep environment and suggest the existence of multiple microbial groups and mechanisms involved in oxidizing methane anaerobically.

The Mars Orbiter Laser Altimeter data has revealed more flow, shield, and small edifice features than were previously mapped from images alone, and Mars Orbiter Camera and Thermal Emission Spectrometer images have helped expand the identification of volcanic features and confirmed the volcanic nature of many features identified in the topography. This study both maps features and characterizes their topographic parameters to constrain the probable eruption style(s) and thus the emplacement mechanics of the small edifices. Prior work in this study has shown that GPS field unit topographic profiles of Quaternary ESRP monogenetic shield volcanoes combined with geochemical sampling may help infer compositional changes in magma supply. In the ESRP, shields with steep summit regions ("caps") show that magmatic compositions are likely more evolved than those at simple shields with consistently low angle flanks. We have been sampling the topography of the ESRP shields at field sampling rates (data points per shield diameter) similar to those available in MOLA topography for the larger Martian edifices, and noting that Martian edifices in some regions also display shields with steep summit regions mixed among the low slope shields, as well as a mix of other features similar to those found in the ESRP such as cinder cones, tuff rings, flow fields, lava tubes, etc. Martian fields display different clusters of topographic characteristics while still fitting into several global parameter trends as well, and it seems plausible that some of the local variations as well as the global trends might be constrained with robust terrestrial ESRP field analogs between geochemistry and topography.

Here we report the presence of Mars-like soils in the extreme arid region of the Atacama Desert. Samples from this region had organic species only at trace levels and extremely low levels of culturable bacteria. Two samples from the extreme arid region were tested for DNA and none was recovered. Incubation experiments, patterned after the Viking labeled-release experiment but with separate biological and nonbiological isomers, show active decomposition of organic species in these soils by nonbiological processes.

The large (D>200 km) buried basins are suggested by "Quasi-Circular Depressions" (QCDs) that are not apparent in image data, and include features up to 3000 km diameter in both the lowlands (Utopia) and highlands (a newly found "Ares Basin"). There are about a dozen QCDs larger than 1000 km diameter. We have placed these large features in a relative age sequence based on superimposed smaller QCD. Only the youngest and most obvious of these (Hellas, Argyre, Isidis) lack magnetic anomalies within their main rings. These all have an N(200) cumulative crater density of 3.5 have many strong magnetic anomalies within their main ring. These older basins likely formed before the main magnetic field died. We have compared our inventory of large QCDs with the distribution of gravity anomalies and with a crustal thickness model which shows many roughly circular areas of thinner crust completely or partly surrounded by narrow regions of thicker crust. These have the structure expected for impact basins, and many of them do correspond to the visible or buried QCDs we previously identified. But there are cases where the crustal thickness feature is offset from the QCD found in topography alone, and there are also several, sometimes large examples of such features which do not coincide with QCDs previously identified. For example, we find several likely buried basins revealed in the crustal thickness data in the Arcadia and Amazonis regions which we did not previously identify, including several features in the 600-1200 km diameter range.

Detailed mapping and sampling of the uppermost of these intervals, the Strelley Pool Chert, shows that it can be interpreted as a multiphase hydrothermal deposit that accumulated in response to a declining temperature regime as the hydrothermal system evolved. The stromatolitic structures were generated by direct precipitation of carbonate from hydrothermal fluids in a relatively deep marine setting where it was modulated by sea floor currents. We find no direct evidence of biogenic mediation in their construction--they are sedimentary structures. Although the stable isotopes of carbon provide data that are consistent with a biogenic origin for the carbonates and cherts, field relations suggest that they were more likely fractionated by abiotic processes at depth in the hydrothermal system. Fractionation may have initially involved Fischer-Tropsch type processes at a depth of almost two kilometers (500 bar) and temperatures of <200 degrees C. Further fractionation of the carbon isotopes may have resulted from de-gassing of hydrothermal fluids at c.1.1 km depth (<300 bar) in the dyke system as they migrated towards the seafloor. Sulfur occurs in two oxidation states as sulfide and sulfate. Field relations suggest that they are derived from two distinct sources and do not necessarily reflect the oxidation state of the ancient ocean and atmosphere. This study questions the remaining evidence for life in the early Archean of Australia. The environmental setting in which life first emerged appears to have been dominated by hydrothermal processes that, because of their unusual chemistry, had the potential to emulate and perhaps synthesize life itself. These hydrothermal systems potentially overwhelm any biospheric geochemical signal and may therefore be the most difficult environments in which to draw the prebiotic-biotic boundary.

High-resolution MOC images on Mars Global Surveyor reveal Martian geomorphic indicators of subsurface ice in unprecedented detail. Polygonal terrain is the dominant indicator of subsurface ice on Mars. Between a latitudinal band of 30 degrees N-65 degrees N, 5,280 narrow-angle MOC images (1.55-12.39 m/pixel) were analyzed and 283 images revealed the presence of polygonal terrain. Distribution of polygonal terrain is consistent with Seibert and Kargel (2001): areas of polygonal terrain are scattered throughout the regional band at low elevations and nearly all latitudes, with a regional concentration in the Casius quadrangle (western Utopia Planitia) between 278 degrees W-258 degrees W and 40 degrees N-50 degrees N. In this region, 74% of the total 132 images analyzed showed the presence of polygonal terrain. However, when the locations of polygonal terrain are compared to GRS hydrogen abundance data the presumed correlation between near subsurface ice and surface expression fails. Polygons are present in areas of low concentrations of near subsurface ice as frequently as they are present in areas of high concentrations of near subsurface ice. High concentrations of polygons in western Utopia Planitia are found to be associated with an area of low hydrogen abundance. Explanations for the anti-correlation can be described by the following models: (1) water ice is absent in the deep subsurface, polygonal terrain is formed from desiccated sediment or unique geologic facies which provide subsurface control of surface expression, (2) there are two distinct ice layers correlating to Martian climate history, a near surface layer correlating to the present Martian climate fluctuations and a deep ground layer correlating to the past Martian climate when the planet was at a higher obliquity, or (3) polygonal terrain exposure is a result of recent erosion and deposition. We favor combinations of these models for the occurrence of polygonal terrain in the 30 degrees N-65 degrees N latitude regions as a whole. However, the extreme obliquity model can explain the data indicating low abundance of subsurface ice as indicated by MGS and the high abundance of polygonal terrain in western Utopia Planitia.

Gaining VNIR, mid-IR, and Raman spectra of such sediments provides compositional information for missions to Mars, as well as ground truthing for reflectance, emittance and Raman spectroscopy of the geology, and perhaps biology, on Mars. C, N, and S isotope analyses provide additional information about biological and chemical activity in the samples studied here and may be utilized in future martian missions. Sediments measured in this study are dominated by feldspar, quartz and pyroxene, and were collected from the perennially ice-covered Lake Hoare in the Taylor Valley and include surface sediments and sediment cores from below oxic and anoxic zones of the lake. Calcite, organics, clays, sulfides, and iron oxides/hydroxides are also present in these igneous sediments and result from chemical and biological alteration processes. Chlorophyll bands are observed in spectra of the sediment-mat layers from the surface of the lake bottom, especially in the anoxic region sediments. Layers of high calcite concentration in the oxic sediments and layers of high pyrite concentration in the anoxic sediments are indicators of periods of active biogeochemical processing in the lake. Micro-Raman spectra have revealed the presence of approximately 5mu m-sized sulfide deposits imbedded in quartz grains in an anoxic sediment. The delta (super 13) C and delta (super 15) N trends show a more complex organic history for the anoxic region sediments than for the oxic region sediments. Correlations are observed between the delta (super 34) S values for sulfate and pyrite and the organic C abundances. Magnetic grains were separated using a hand magnet for the surface sand and one oxic region sediment. The VNIR spectra of the magnetic grains in each sample are substantially darker than spectra of the bulk sediments, the mid-IR spectra of the magnetic grains do not exhibit the quartz bands present in the bulk sediment spectra and Raman spectra show the presence of magnetite (and maybe some Ti-spinel) in the magnetic grains. However, all three spectroscopic techniques show that other minerals including feldspar, pyroxene, Fe-Ti oxide, and Fe-rich clays are also present in the magnetic grains.

Because of this, the Dry Valleys have been, and still are, the focus of many areas of research. In a 1983 study [1], weathering products and chemistry were documented at intervals in a soil pit ( approximately 80 cm deep) in Wright Valley. We are re-examining that work in view of more recent data from Mars orbital and meteorite studies (note: in 1983, it was not yet established that any meteorites came from Mars). Results of the Wright Valley work seem to be consistent with what is now known or postulated about Mars. Orbital data indicate the presence of water ice just beneath the martian surface [2, 3]. Similarly, in the Wright Valley soil, the water content (-40 to 110 degrees C) at the surface is much lower than that at depth, and water decreases upward even within the permanently frozen zone (>40 cm). Water-soluble species in Wright Valley also increase upward. Most changes occur above the permafrost but chemical trends in the Wright Valley soil indicate that aqueous geochemistry is active even in permanently frozen portions. Mars remote sensing data suggest that total amounts of alteration of original igneous rocks on Mars may be low [5]. The top 1-2 cm of the Wright Valley soil is highly depleted in salts compared to the underlying soil, however; it is likely that Mars has analogous characteristics. Mars meteorites have proven that traces of low-temperature aqueous alteration have occurred on Mars [6]; secondary phases in the meteorites are much like those in Wright Valley soil (calcite, Ca-sulfate, halite, and secondary silicates). The extreme variations in composition and mineralogy over a small vertical scale are characteristic of the Wright Valley soil column. Lateral environmental differences in the Dry Valleys also exist. They are responsible for variations in biota; areas lacking life have been apparently identified [5]. The possibility that such small-scale variations are present on Mars should be considered carefully in the search for life there.

These BRSs are defined by quasi-circular raised annuli 50-500 m in diameter [1]. They occasionally have small peaks at their centers with surrounding moats, but more often have central depressions. At least two distinct populations of BRSs exist: one around Odessa, WA and another west of Tokio, WA. The structures near Odessa typically have concentric rings made up of discontinuous arcuate ridges. Those near Tokio are generally single-ringed structures with little topography and significant loess infill; they are smaller and less circular than the Odessa population. Previous researchers have hypothesized that BRSs form by either the sagging and foundering of crust over an active lava flow or by the interaction of ground water with lava causing venting, doming, and cracking of the crust. In this study we documented in detail 5 multi-ringed BRSs in the Odessa area. In each case the BRS consists of entablature with columns that plunge steeply away from the center and auto-intruded dikes with larger columns that plunge at a moderate angle toward the center of the ring structure. We also examined a purported cross section of a BRS near Banks Lake. This outcrop shows a funnel-shaped depression in the entablature with auto-intruded dikes that have orientations similar to those described above. On either side of the central depression, the lavas appear to be more finely fractured, suggesting rapid cooling. Based on these findings we hypothesize that the BRSs formed where advancing lava flows were diverted around local concentrations of water. Circular features that are similar in shape, size, and distribution to the Tokio BRSs have been observed in Athabasca Valles, Mars, a region where young ( approximately 10 Ma) lava flows have been eroded by even more recent catastrophic floods. The apparent role of water in the formation of the BRSs on Earth has important implications for understanding the spatial and temporal distribution of recent water on Mars.

Here we report that recent data show that J (sub 2) has been rapidly returning toward "normal" (with PGR considered) since early 2001. In search of the geophysical and climatic causes for this "1998-2002 J (sub 2) anomaly," we report an oceanographic event that took place in the extratropic north and south Pacific basins that was found to match remarkably well with the time evolution of the anomaly. We examine the leading (nonseasonal, extratropic Pacific) Empirical Orthogonal Function/Principal Component modes in the sea-surface height (SSH) data from TOPEX/Poseidon, sea surface temperature (SST) data from the National Center for Environmental Predictions, and output fields of the Estimating the Circulation and the Climate of the Ocean (ECCO) ocean general circulation model (OGCM), including ocean bottom pressure (OBP) and temperature and salinity profiles. The phenomenon appears to be part of the Pacific Decadal Oscillation, and temporal correlations are made. However, quantitatively, the OBP field of the ECCO model predicts a J (sub 2) anomaly that is smaller in magnitude than the observed by a factor of about 3. We discuss various possibilities for reconciling this discrepancy in terms of inadequacies of present OGCMs and considering other geophysical contributions; a complete resolution of the J (sub 2) enigma awaits further studies.

This study uses the NASA upward flame propagation test and the cone calorimeter test to evaluate the application of polyimide foam as a fire barrier for spacecraft cushion materials. The flame propagation test results demonstrate that a thin-layer of polyimide foam (3-mm thick) could totally stop the flame spread on the underneath polyurethane foam in an environment containing 30% oxygen. The cone calorimeter test results show that polyimide foam increased the minimum heat flux for ignition of a cushion sample from 27 to 48 kW/m super(2). This suggests that application of polyimide foam can significantly reduce the ignition risk. It was also found that polyimide foam significantly reduced the peak heat release rate, mass burning rate, and the generation of carbon monoxide and smoke in the flaming combustion. For polyimide foam-covered polyurethane, smoldering combustion was insignificant at 25 and 35 kW/m super(2) incident heat fluxes; it became more important when the incident heat flux reached 45 kW/m super(2). The smoldering combustion of polyurethane foam and polyimide foam-covered polyurethane could not be self-sustaining if the external heat source was removed.

Part I: Equatorial Heat Content Changes Induced by the Off-Equatorial Wind AN - 19183817; 5756417 AB - A reduced-gravity shallow-water model, an oceanic general circulation model for the Pacific region, and the analytical model of the equatorial beta plane bounded in the zonal direction are used to investigate the equatorial thermocline response to tropical and subtropical wind stress forcing. The results show that the wind stress forcing in the tropical and subtropical region can generate a nearly zonal uniform thermocline depth change in the equatorial region. The response timescale is longer when the wind stress is placed farther away from the equator. There exist latitude bands around 10 degree -15 degree N and 10 degree -15 degree S where the forcing can cause a relatively large equatorial response. When the forcing is located in the eastern basin, the response timescale is longer and its magnitude is larger than the case when the forcing is located in the western basin. Thus the eastern tropical to subtropical region is a relatively effective area for off-equatorial wind stress to generate an equatorial thermocline response. When the wind stress forcing has a longer period, the response of the equatorial thermocline has a larger magnitude. The results from this study's numerical experiments and the analytical solution are consistent. The present study has implications for the broad-scale ocean-atmosphere interaction in the tropical region.

The rms error of the derived surface temperatures when compared with in situ data ranges from 1.5 to 3 K over the 20-yr period. Average temperature trends are generally positive at 0.33 plus or minus 0.16 degree C decade-1 over sea ice, 0.50 plus or minus 0.22 degree C decade-1 over Eurasia, and 1.06 plus or minus 0.22 degree C decade-1 over North America. The trend is slightly negative and insignificant at -0.09 plus or minus 0.25 degree C decade-1 in Greenland with the negatives mainly at high elevations. The trends are also predominantly positive in spring, summer, and autumn causing the lengthening of the melt season by 10-17 days per decade while they are generally negative in winter. The longer-term in situ surface temperature data shows that the 20-yr trend is 8 times larger than the 100-yr trend suggesting a rapid acceleration in the warming that may be associated with the recent change in phase of the Arctic Oscillation that has been linked to increasing greenhouse gases in the atmosphere.

The four sectors represent long-range transport from the west (WSW), regional circulation over the western Pacific and Southeast Asia (SE Asia), polluted transport from northern Asia with substantial sea salt at low altitudes (NNW) and a substantial amount of dust (Channel). WSW has generally low mixing ratios at both middle and high altitudes, with the bulk of the aerosol mass due to non-sea-salt water-soluble inorganic species. Low altitude SE Asia also has low mean mixing ratios in general, with the majority of the aerosol mass comprised of non-sea-salts, however, soot is also relatively important in this region. NNW had the highest mean sea salt mixing ratios, with the aerosol mass at low altitudes (<2 km) evenly divided between sea salts, non-sea-salts, and dust. The highest mean mixing ratios of water-soluble ions and soot were observed at the lowest altitudes (<2 km) in the Channel sector. The bulk of the aerosol mass exported from Asia emanates from Channel at both low and midaltitudes, due to the prevalence of dust compared to other sectors. Number densities show enhanced fine particles for Channel and NNW, while their volume distributions are enhanced due to sea salt and dust. Low-altitude Channel exhibits the highest condensation nuclei (CN) number densities along with enhanced scattering coefficients, compared to the other sectors. At midaltitudes (2-7 km), low mean CN number densities coupled with a high proportion of nonvolatile particles ( greater than or equal to 65%) observed in polluted sectors (Channel and NNW) are attributed to wet scavenging which removes hygroscopic CN particles. Low single scatter albedo in SE Asia reflects enhanced soot.

Large radiance enhancements were observed at 5.3 mu m, which are due to emission from the vibration-rotation bands of nitric oxide (NO). The emission by NO is indicative of the conversion of solar energy to infrared radiation within the atmosphere and represents a 'natural thermostat' by which heat and energy are efficiently lost from the thermosphere to space and to the lower atmosphere. We describe the SABER observations at 5.3 mu m and their interpretation in terms of energy loss. The infrared enhancements remain only for a few days, indicating that such perturbations to the thermospheric state, while dramatic, are short-lived.

The computed ozone budget explicitly accounts for stratosphere/troposphere exchange (STE) and in situ ozone production using on-line chemical calculations. The east Asian O sub(3) budget is computed during the period from 7 March to 12 April 2001. Gross formation dominates STE by a ratio of 7 to 1 in east Asia during TRACE-P. However, this ratio is strongly influenced by altitude of the tropopause. Approximately 30% of the ozone that is advected across the tropopause over east Asia is subsequently advected out over the western Pacific within the upper 4 km of the troposphere by the Japan jet. The average net photochemical production (gross formation-gross destruction) within the regional domain is 0.37 Tg d super(- 1) or 7% of the average flux at the eastern boundary of the domain during the TRACE-P time period. The budget analysis shows a very close balance between sources and sinks within the RAQMS regional domain during the TRACE-P time period. This balance results in very small average accumulation ( similar to 1 Tg) of O sub(3) in the east Asian region and very little net export averaged over the period (0.03 Tg d super(-1)). The low ozone export from east Asia predicted by RAQMS during TRACE-P is a consequence of relatively high dry deposition rates, which are 37% of the gross ozone formation (1.469 Tg d super(-1)) within the TRACE-P regional domain.

AN - 75711343; 14510851 AB - Microbial characterization of the Mars Odyssey spacecraft and the Kennedy Space Center Spacecraft Assembly and Encapsulation Facility II (SAEF-II) was carried out by both culture-based and molecular methods. The most dominant cultivable microbes were species of Bacillus, with comamonads, microbacteria and actinomycetales also represented. Several spore-forming isolates were resistant to gamma-radiation, UV, H2O2 and desiccation, and one Acinetobacter radioresistens isolate and several Aureobasidium, isolated directly from the spacecraft, survived various conditions. Sequences arising in clone libraries were fairly consistent between the spacecraft and facility; predominant genera included Variovorax, Ralstonia and Aquaspirillum. This study improves our understanding of the microbial community structure, diversity and survival capabilities of microbes in an encapsulation facility and physically associated with colocated spacecraft.

AN - 73653208; 12968931 AB - Chromosome aberrations were investigated in human lymphocytes after in vitro exposure to 1H-, 3He-, 12C-, 40Ar-, 28Si-, 56Fe-, or 197Au-ion beams, with LET ranging from approximately 0.4-1393 keV/microm in the dose range of 0.075-3 Gy. Dose-response curves for chromosome exchanges, measured at the first mitosis postirradiation using fluorescence in situ hybridization (FISH) with whole-chromosome probes, were fitted with linear or linear-quadratic functions. The relative biological effectiveness (RBE) was estimated from the initial slope of the dose-response curve for chromosomal damage with respect to low- or high-dose-rate gamma rays. Estimates of RBEmax values for mitotic spreads, which ranged from near 0.7 to 11.1 for total exchanges, increased with LET, reaching a maximum at about 150 keV/microm, and decreased with further increase in LET. RBEs for complex aberrations are undefined due to the lack of an initial slope for gamma rays. Additionally, the effect of mitotic delay on RBE values was investigated by measuring chromosome aberrations in interphase after chemically induced premature chromosome condensation (PCC), and values were up to threefold higher than for metaphase analysis.

AN - 73644820; 12968932 AB - Confluent human fibroblast cells (AG1522) were irradiated with gamma rays, 490 MeV/nucleon silicon ions, or iron ions at either 200 or 500 MeV/nucleon. The cells were allowed to repair at 37 degrees C for 24 h after exposure, and a chemically induced premature chromosome condensation (PCC) technique was used to condense chromosomes in the G2 phase of the cell cycle. Incomplete and complex exchanges were analyzed in the irradiated samples. To verify that chromosomal breaks were truly unrejoined, chromosome aberrations were analyzed using a combination of whole-chromosome specific probes and probes specific for the telomere region of the chromosome. Results showed that the frequency of unrejoined chromosome breaks was higher after irradiation with the heavy ions of high LET, and consequently the ratio of incomplete to complete exchanges increased steadily with LET up to 440 keV/microm, the highest LET included in the present study. For samples exposed to 200 MeV/nucleon iron ions, chromosome aberrations were analyzed using the multicolor FISH (mFISH) technique, which allows identification of both complex and truly incomplete exchanges. Results of the mFISH study showed that 0.7 and 3 Gy iron ions produced similar ratios of complex to simple exchanges and incomplete to complete exchanges; these ratios were higher than those obtained after exposure to 6 Gy gamma rays. After 0.7 Gy of iron ions, most complex aberrations were found to involve three or four chromosomes, which is a likely indication of the maximum number of chromosome domains traversed by a single iron-ion track.

AN - 71509876; 14676402 AB - We report here a bystander effect in chromosomal damage using He-ion microbeam. Human-hamster hybrid cells were irradiated with a precision He-ion microbeam generated by the Columbia microbeam system. When 20% of the cells were exposed to single He ion, the incidence of cells with chromatid-type breaks detected with the PCC technique was covered wide range from 0 to 6 breaks per cell. In contrast, the distribution showed a mixed two-peak pattern, such as non-exposed and all-cell exposed patterns, under the condition of assuming no bystander effect by treating with an effective inhibitor of cell-cell communication. These findings provide clear evidence that single He-ion irradiated cells can induce bystander chromosomal alterations in neighboring cells not directly hit by He ion.

AN - 71474993; 14676404 AB - DNA double strand break (DSB) causes many cytotoxic effects such as cellular lethality, somatic mutation, and carcinogenesis. Fidelity of DSB repair is a important factor that determines the quality of genomic stability. It is known that the most of DSBs are properly repaired on the earth, however, little is known whether those are rejoined at the same fidelity even under the space environment. One of the DSB repair pathway, homologous recombination (HR), allows the cells to repair their DSBs with error free. Therefore, the efficiency of HR is a good index to assess the fidelity of DSB repair. In order to clarify the effect of gravity stress on HR pathway, we established a cell line that can detect a site-specific DNA repair via HR. The cells carrying a reporter construct for HR were incubated under hypergravity condition after induction of site specific DSB. Our preliminary results suggest that the gravity stress may affect the HR efficiency.

AN - 71473064; 14676366 AB - One of the important concerns for astronauts in space environment is cancer risk associated with cosmic radiation, including heavy particle carbon-ions. But little information on cancer risk is available. In the present study, we investigated the induction of and cellular and molecular characteristics of T-cell lymphomas of B6C3F1 mice induced by carbon-ions and X-rays. The incidence, the latent period and the surface expression of T-cell differentiation antigens were similar between carbon-ion- and X-ray-induced lymphomas. The size of T-cell lymphomas induced by carbon-ions was significantly smaller than that by X-rays. Molecular analysis indicated that high frequency of loss of heterozygosity (LOH) was found on chromosomes 4, 11, 12 and 19 in both lymphomas. Interestingly, the frequency of LOH on chromosome 11 was much higher, but that on chromosome 12 was lower in carbon-ion-induced T-cell lymphomas than in X-ray-induced ones. These results indicate that mechanistic differences may exist between carbon-ion- and X-ray-induced lymphomagenesis.

AN - 71473031; 14676365 AB - We have been studying LET and ion species dependence of RBE values in cell killing and mutation induction. Normal human skin fibroblasts were irradiated with heavy-ion beams such as carbon (290 Mev/u and 135 Mev/u), neon (230 Mev/u and 400 Mev/u), silicon (490 Mev/u) and iron (500 Mev/u) ion beams, generated by Heavy Ion Medical Accelerator in Chiba (HIMAC) at National Institute of Radiological Sciences (NIRS). Cell killing effect was detected as reproductive cell death using a colony formation assay. Mutation induction in hprt locus was detected to measure 6-thioguanine resistant colonies. The RBE-LET curves of cell killing and mutation induction were different each ion beam. So, we plotted RBE for cell killing and mutation induction as function of Z*2/beta2 instead of LET. RBE-Z*2/beta2 curves of cell killing indicated that the discrepancy of RBE-LET curves was reconciled each ion species. But RBE-Z*2/beta2 curves of mutation induction didn't corresponded between carbon- and silicon-ion beams. These results suggested that different biological endpoints may be suitable for different physical parameter, which represent the track structure of energy deposition of ion beams.

AN - 71471691; 14676408 AB - To investigate effects of low dose heavy particle radiation to CNS system, we adopted mouse neonatal brain cells in culture being exposed to heavy ions generated by HIMAC at NIRS and BNL. The applied dose varied from 0.05 Gy up to 2.0 Gy. The subsequent biological effects were evaluated by an induction of apoptosis focusing on the dependencies of (1) the animal strains with different radiation sensitivities, and (2) LET with different nuclei. Of the three mouse strains, SCID, B6 and C3H, used for brain cell culture, SCID was the most sensitive and C3H the least sensitive to both X-ray and carbon ion ( 290 MeV/n) as evaluated by 10% apoptotic criterion. However, the sensitivity differences among the strains were much smaller in case of carbon ion comparing to that of X-ray. Regarding the LET dependency, the sensitivity was compared with using C3H and B6 cells between the carbon (13 keV/micrometers) and neon (70 keV/micrometers) ions. Carbon (290 MeV/n) did not give a detectable LET dependency from the criterion whereas the neon (400 MeV/n) showed 1.4 fold difference for both C3H and B6 cells. Although a LET dependency was examined by using the most sensitive SCID cells, no significant difference was detected.

AN - 71468703; 14676403 AB - A single cell irradiation system has been developed at JAERI-Takasaki to elucidate biological effects of low dose and low dose-rate space radiation. The system has been installed at high-energy collimated heavy-ion microbeam apparatus under a vertical beam line of AVF-cyclotron accelerator. Individual mammalian cultured cells are irradiated in the atmosphere on the cell dish, the bottom of which is made of ion-track-detector TNF-1 (modified CR-39), with a single or precise numbers of 11.5 MeV/u 40Ar13+, 13.0 MeV/u 20Ne7+, and 18.3 MeV/u 12C5+ ions. Positional data of the target cells are obtained at the off-line microscope before irradiation. Targeting and irradiation of the cells are performed automatically at the on-line microscope of the microbeam apparatus according to the obtained data. About 50-100 cells are irradiated in several minutes. The number of ions traversed the cells attached on the ion track detector were counted with a plastic scintillator-photomultiplier tube assembly and a constant fraction discriminator. Immediately after the irradiation, the bottom of the cell dish was etched at 37 degrees C to check the spatial distribution of irradiated ions. The one batch of cell sample is treated in about 1 hr including the phases of cell finding, irradiation, and etching/observing of the ion tracks.

AN - 71405168; 14649627 AB - Experiments were conducted in a Mars simulation chamber (MSC) to characterize the survival of endospores of Bacillus subtilis under high UV irradiation and simulated martian conditions. The MSC was used to create Mars surface environments in which pressure (8.5 mb), temperature (-80, -40, -10, or +23 degrees C), gas composition (Earth-normal N2/O2 mix, pure N2, pure CO2, or a Mars gas mix), and UV-VIS-NIR fluence rates (200-1200 nm) were maintained within tight limits. The Mars gas mix was composed of CO2 (95.3%), N2 (2.7%), Ar (1.7%), O2 (0.2%), and water vapor (0.03%). Experiments were conducted to measure the effects of pressure, gas composition, and temperature alone or in combination with Mars-normal UV-VIS-NIR light environments. Endospores of B. subtilis, were deposited on aluminum coupons as monolayers in which the average density applied to coupons was 2.47 x 10(6) bacteria per sample. Populations of B. subtilis placed on aluminum coupons and subjected to an Earth-normal temperature (23 degrees C), pressure (1013 mb), and gas mix (normal N2/O2 ratio) but illuminated with a Mars-normal UV-VIS-NIR spectrum were reduced by over 99.9% after 30 sec exposure to Mars-normal UV fluence rates. However, it required at least 15 min of Mars-normal UV exposure to reduce bacterial populations on aluminum coupons to non-recoverable levels. These results were duplicated when bacteria were exposed to Mars-normal environments of temperature (-10 degrees C), pressure (8.5 mb), gas composition (pure CO2), and UV fluence rates. In other experiments, results indicated that the gas composition of the atmosphere and the temperature of the bacterial monolayers at the time of Mars UV exposure had no effects on the survival of bacterial endospores. But Mars-normal pressures (8.5 mb) were found to reduce survival by approximately 20-35% compared to Earth-normal pressures (1013 mb). The primary implications of these results are (a) that greater than 99.9% of bacterial populations on sun-exposed surfaces of spacecraft are likely to be inactivated within a few tens of seconds to a few minutes on the surface of Mars, and (b) that within a single Mars day under clear-sky conditions bacterial populations on sun-exposed surfaces of spacecraft will be sterilized. Furthermore, these results suggest that the high UV fluence rates on the martian surface can be an important resource in minimizing the forward contamination of Mars. c2003 Elsevier Inc.

New measurements of albite (Ab (sub 98) ) presented here display major spectral absorptions between 1000-1250 cm (super -1) (8-10 mu m) (due to Si-O antisymmetric stretch motions of the silica tetrahedra) and weaker absorptions between 350-700 cm (super -1) (14-29 mu m) (due to Si-O-Si octahedral bending vibrations). Many of these features persist to higher pressures compared to similar features in measurements of shocked anorthite, consistent with previous thermal infrared absorption studies of shocked feldspars. A transparency feature at 855 cm (super -1) (11.7 mu m) observed in powdered albite spectra also degrades with increasing pressure, similar to the 830 cm (super -1) (12.0 mu m) transparency feature in spectra of powders of shocked anorthite. Linear deconvolution models demonstrate that combinations of common mineral and glass spectra can replicate the spectra of shocked anorthite relatively well until shock pressures of 20-25 GPa, above which model errors increase substantially, coincident with the onset of diaplectic glass formation. Albite deconvolutions exhibit higher errors overall but do not change significantly with pressure, likely because certain clay minerals selected by the model exhibit absorption features similar to those in highly shocked albite. The implication for deconvolution of thermal infrared spectra of planetary surfaces (or laboratory spectra of samples) is that the use of highly shocked anorthite spectra in end-member libraries could be helpful in identifying highly shocked calcic plagioclase feldspars.

Shewanella oneidensis strain MR-1 cells were inoculated with lactate as the electron donor and Fe(III) in smectite as the electron acceptor. The extent of Fe(III) reduction was observed to reach up to 26%. Reduction proceeded via association of live bacterial cells with smectite. At the end of incubation, a large fraction of starting smectite was transformed to euhedral flakes of biogenic smectite with different morphology, structure, and composition. Lattice-fringe images obtained from environmental cell transmission electron microscope displayed a decrease of layer spacing from 1.5+ or -0.1 nm for the unreduced smectite to 1.1+ or -0.1 nm for the reduced smectite. The biogenic smectite contained more abundant interlayer cations, apparently as a result of charge compensation for the reduced oxidation state of Fe in the octahedral site. To capture the dynamics of smectite reduction, a separate experiment was designed. The experiment consisted of several systems, where various combination of carbon source (lactate) and different concentrations of AQDS, an electron shuttle, were used. Selected area electron diffraction patterns of smectite showed progressive change from single-crystal patterns for the control experiment (oxidized, unaltered smectite), to diffuse ring patterns for the no-carbon experiment (oxidized, but altered smectite), to well-ordered single crystal pattern for the experiment amended with 1 mM AQDS (well crystalline, biogenic smectite). Large crystals of vivianite and fine-grained silica of biogenic origin were also detected in the bioreduced sample. These data collectively demonstrate that microbial reduction of Fe(III) in smectite was achieved via dissolution of smectite and formation of biogenic minerals. The microbially mediated mineral dissolution-precipitation mechanism has important implications for mineral reactions in natural environments, where the reaction rates may be substantially enhanced by the presence of bacteria.

The surveys were compared to quantify the magnitudes and patterns of erosion and accretion in both natural areas and areas that had been subjected to major restoration. Wave runup exceeded the elevation of the entire Isles Dernieres barrier chain creating overwash deposits that, in places, were driven landward approximately 300 m. This response was not as severe as observed during Hurricane Andrew in 1992 when the Isles Dernieres were completely and continuously inundated and sand bodies were driven landward on the order of 1 km. Based on a comparison of surveys before and after the combined impacts of Lili and Isidore, the largest shoreline change occurred at the east end of East Island and reached approximately 130 m of erosion.

But this mean value conceals the substantial complexity of observed climate change, which is seasonally- and diurnally-biased, decadally-variable and geographically patchy. In particular, over the last 50 years three high-latitude areas have undergone recent rapid regional (RRR) warming, which was substantially more rapid than the global mean. However, each RRR warming occupies a different climatic regime and may have an entirely different underlying cause. We discuss the significance of RRR warming in one area, the Antarctic Peninsula. Here warming was much more rapid than in the rest of Antarctica where it was not significantly different to the global mean. We highlight climate proxies that appear to show that RRR warming on the Antarctic Peninsula is unprecedented over the last two millennia, and so unlikely to be a natural mode of variability.

Nili Fossae has been interpreted as a complex of grabens and fractures related to the formation of the Isidis impact basin. We propose that post-impact faulting of this area has exposed subsurface layers rich in olivine. Linear mixture analysis of Thermal Emission Spectrometer spectra shows surface exposures of 30% olivine, where the composition of the olivine ranges from Fo (sub 30) to Fo (sub 70) .

This design methodology is based on the concepts of the characteristic failure signature (CFS), cumulative-damage states and a load-drop sequence that characterize the stress-strain response and progressive accumulation of damage. The cumulative damage mechanics is based on the three-dimensional laminate analysis that is used to predict nonlinear response of composites, accumulation of damage and failure behavior. An earlier-developed nonlinear analysis involves an incremental formulation that couples the three-dimensional laminate analysis with a progressive ply-failure methodology, which has been tested in the World-Wide Exercise on Composites Failure Theories. The failure signatures are shown to have unique 'safety features'that depend on the ply stacking sequence and predominant loading. To refine the analysis of micromechanical damage a model for the macro-to-micro coupling is introduced. Various examples of failure envelopes, characteristic failure signatures, a safety criterion and the 'safe' CFSs that lead to the desired controlled failures are discussed for symmetric balanced laminates.

Estimates of aboveground dry biomass for different types of land cover in each county or state were converted directly to estimates of standing carbon. A portable, inexpensive laser that measures forest canopy height and canopy cover was also used to identify and map mature forest stands that might support the Delmarva fox squirrel (Sciurus niger cinereus), an endangered species. Merchantable volume estimates were within 24 percent of US Forest Service estimates at the county level and within 15 percent statewide. Total aboveground dry biomass estimates were within 19 percent of US Forest Service estimates at the county level and within 16 percent statewide. Various types of impervious surfaces (roofs, concrete, asphalt) and open water were tallied along the flight lines to estimate areal coverage statewide, by land cover and county.

The calibration is based on a National Institute of Standards and Technology traceable dew point hygrometer using relatively high humidity and short optical path length. Two near-infrared water vapor absorption lines of widely different strengths are used to increase the dynamic range of the instrument in the course of a flight. The laboratory results are incorporated into a numerical model of the second harmonic spectrum for each of the two spectral window regions using spectroscopic parameters from the HITRAN database and other sources, allowing water vapor retrieval at upper tropospheric and lower stratospheric temperatures and humidity levels. The data retrieval algorithm is simple, numerically stable, and accurate. A comparison with other water vapor instruments on board the NASA DC-8 and ER-2 aircraft is presented.

Remote measurements were made with an airborne lidar to provide O sub(3) and multiple-wavelength aerosol backscatter profiles from near the surface to above the tropopause along the flight track. In situ measurements of O sub(3), aerosols, and a wide range of trace gases were made onboard the DC-8. Five-day backward trajectories were used in conjunction with the O sub(3) and aerosol distributions on each flight to indicate the possible origin of observed air masses, such as from biomass burning regions, continental pollution, desert regions, and oceanic regions. Average latitudinal O sub(3) and aerosol scattering ratio distributions were derived from all flights west of 150 degree E, and these distributions showed the average latitude and altitude dependence of different dynamical and chemical processes in determining the atmospheric composition over the western Pacific. TRACE-P (TP) showed an increase in the average latitudinal distributions of both O sub(3) and aerosols compared to PEM-West B (PWB), which was conducted in February-March 1994. O sub(3), aerosol, and potential vorticity levels were used to identify nine air mass types and quantify their frequency of occurrence as a function of altitude. This paper discusses the characteristics of the different air mass types encountered during TP and compares them to PWB. These results confirmed that most of the O sub(3) increase in TP was due to photochemistry. The average latitudinal eastward O sub(3) flux in the western Pacific during TP was found to peak near 32 degree N with a total average O sub(3) flux between 14 and 46 degree N of 5.2 Tg/day. The eastward total CO flux was calculated to be 2.2 Tg-C/day with 6% estimated from Asia. The Asian flux of CO sub(2) and CH sub(4) was estimated at 4.9 and 0.06 Tg-C/day.

The CO sub(2 )spatial distributions were notably influenced by cyclogenesis-triggered transport of regionally polluted continental air masses. Examination of the CO sub(2) to C sub(2)H sub(2)/CO ratio indicated rapid outflow of combustion-related emissions in the free troposphere below 8 km. Although the highest CO sub(2) mixing ratios were measured within the Pacific Rim region, enhancements were also observed further east over the open ocean at locations far removed from surface sources. Near the Asian continent, discrete plumes encountered within the planetary boundary layer contained up to 393 ppmv of CO sub(2). Coincident enhancements in the mixing ratios of C sub(2)Cl sub(4), C sub(2)H sub(2), and C sub(2)H sub(4) measured concurrently revealed combustion and industrial sources. To elucidate the source distributions of CO sub(2), an emissions database for Asia was examined in conjunction with the chemistry and 5-day backward trajectories that revealed the WNW/W sector of northeast Asia was a major contributor to these pollution events. Comparisons of NOAA/CMDL and JMA surface data with measurements obtained aloft showed a strong latitudinal gradient that peaked between 35 degree and 40 degree N. We estimated a net CO sub(2) flux from the Asian continent of approximately 13.93 Tg C day super(-1) for late winter/early spring with the majority of the export (79%) occurring in the lower free troposphere (2-8 km). The apportionment of the flux between anthropogenic and biospheric sources was estimated at 6.37 Tg C day super(-1) and 7.56 Tg C day super(-1), respectively.

AN - 71506036; 14672086 AB - The wheat straw, an inedible biomass that can be continuously produced in a space vehicle has been used to produce activated carbon for effective control of NOx emissions from the incineration of wastes. The optimal carbonization temperature of wheat straw was found to be around 600 degrees C when a burnoff of 67% was observed. The BET surface area of the activated carbon produced from the wheat straw reached as high as 300 m2/g. The presence of oxygen in flue gas is essential for effective adsorption of NO by activated carbon. On the contrary, water vapor inhibits the adsorption efficiency of NO. Consequently, water vapor in flue gas should be removed by drying agents before adsorption to ensure high NO adsorption efficiency. All of the NO in the flue gas was removed for more than 2 h by the activated carbons when 10% oxygen was present and the ratio of carbon weight to the flue gas flow rate (W/F) was 30 g min/L, with a contact time of 10.2 s. All of NO was reduced to N2 by the activated carbon at 450 degrees C with a W/F ratio of 15 g min/L and a contact time of 5.1 s. Reduction of the adsorbed NO also regenerated the activated carbon, and the regenerated activated carbon exhibited an improved NO adsorption efficiency. However, the reduction of the adsorbed NO resulted in a loss of carbon which was determined to be about 0.99% of the activated carbon per cycle of regeneration. The sufficiency of the amount of wheat straw in providing the activated carbon based on a six-person crew, such as the mission planned for Mars, has been determined. This novel approach for the control of NOx emissions is sustainable in a closed system such as the case in space travel. It is simple to operate and is functional under microgravity environment.

Motion along these megascale accommodation zones enabled the different arms of the Afar RRR (rift-rift-rift) triple junction to join together. An arcuate accommodation zone approximately 45 km wide and approximately 60 km long marks the transition from the N25 degrees W-striking Southern Red Sea Rift trend in the western Afar margin to the N25 degrees E-striking Main Ethiopian Rift. Another accommodation zone approximately 80 km long marks the transition between the northeast- to north-northeast-trending Main Ethiopian Rift and the nearly east-trending Gulf of Aden. The positions of accommodation zones where rift orientations change by approximately 50 degrees suggest that they served as soft linking points between the kinematically "misaligned" arms of the triple junction during the initial breakup of the Afro-Arabian dome. We use structural features to infer the present location of the triple junction in the Lake Abhe area. On the basis of the location of the paleo-triple junction, deduced from the position of accommodation zones and geomorphic considerations, it is estimated that the Afar triple junction has migrated approximately 1.5 degrees ( approximately 160 km) in a north- northeast direction with respect to the African (Nubian) plate. The estimated amount of migration of the Afar triple junction is less than the 200 km migration expected from plate-kinematic analysis. This discrepancy suggests either a slower rate of spreading than the current approximately 1.6 cm/yr (Africa-Arabia) during the early phase of rifting or a later early Miocene rather than Oligocene-Miocene age for the initiation of tectonic activity in the triple junction.

All of the models give reasonable agreement with observed global temperature change during 1951-2000, but the quasi-isopycnal ocean E mixes heat more deeply and hence sequesters heat more effectively on the century timescale. Global surface warming in the next 50 yr is only 0.3 degrees -0.4 degrees C with this ocean in simulations driven by an "alternative scenario" climate forcing (1.1 W m (super -2) in the next 50 yr), only half as much as with ocean B. From the different models the authors estimate that the earth was out of radiation balance by about 0.18 W m (super -2) in 1951 and is now out of balance by about 0.75 W m (super -2) . This energy imbalance, or residual climate forcing, a consequence of deep ocean mixing of heat anomalies and the history of climate forcings, is a crucial measure of the state of the climate system that should be precisely monitored with full-ocean temperature measurements.

Plagioclase compositions are approximately An (sub 98) , and are even more calcic than those in cumulate eucrites. Pyroxene does not show pigeonite-to-orthopyroxene inversion textures, suggesting different crystallization conditions than those of cumulate eucrites. Mn-Cr isotopic analyses determined initial (super 53) Mn/ (super 55) Mn = (4.6+ or -1.7)X10 (super -6) and initial epsilon ( (super 53) Cr) (sub I) = 0.25+ or -0.17 in A881394. This initial (super 53) Mn abundance corresponds to a formation interval Delta t (sub LEW) = -6+ or -2 Ma relative to the LEW86010 angrite, implying an "absolute" age of 4564+ or -2 Ma. Both the initial (super 53) Mn abundance and the initial epsilon ( (super 53) Cr) (sub I) value for A881394 are identical to those previously determined for the HED parent body at the time of its differentiation. Al-Mg isotopic analyses determined initial (super 26) Al/ (super 27) Al = (1.18+ or -0.14)X10 (super -6) , from which a formation interval Delta t (sub CAI) = 3.95+ or -0.13 Ma is calculated relative to the canonical value (super 26) Al/ (super 27) Al = 5X10 (super -5) for CAI. Combining this formation interval with a recently reported Pb-Pb age of 4567.2+ or -0.6 Ma for CAI gives 4563.2+ or -0.6 Ma as the age of A881394, in excellent agreement with the age based on the Mn-Cr formation interval. Alternatively, the (super 53) Mn and (super 26) Al formation intervals of A881394 allow the Mn-Cr and Al-Mg timescales to be intercalibrated, suggesting that an "absolute" CAI age of 4568 Ma is most consistent with the 4558 Ma Pb-Pb age of LEW86010. The initial (super 26) Al abundance existing in A881394 would have been insufficient to cause global melting in the HED parent body (probably asteroid 4 Vesta). Nevertheless, it could have been derived by radioactive decay over only approximately 2 Ma from an abundance that would have been sufficient to cause global melting. The higher value of molar Mg/(Mg+Fe) = 0.57 for A881394 than those of the ordinary (basaltic) eucrites (Mg/(Mg+Fe) = 0.30-0.42) suggests additional factors may have been important for magma genesis on the parent body. If (super 26) Al were the only heat source, partial melting would have been the major process in the interior of the parent body, and Mg/(Mg+Fe) would be lower in the melts than in the primordial source material. Late-stage accretion could have supplied relatively magnesian primordial material to the surface of the parent body, thereby increasing Mg/(Mg+Fe) in a shallow magma ocean from which A881394 crystallized, and also may have augmented (super 26) Al heating. The granulitic texture of A881394 may have been produced during residence in the thin, earliest, crust, kept hot by the magma beneath it. If (super 26) Al was, nevertheless, the major heat source for asteroidal melting, it may account for declining post-accretion heating of main belt asteroids with increasing heliocentric distance.

A significant majorite component appears in garnet at pressures as low as approximately 5 GPa, substantially lower than reported in previous studies, as evidenced by decreasing Al and increasing octahedral Si and Fe per formula unit with increasing pressure. The majorite component in our garnets exerts a clear influence on trace element partitioning, most strongly for the heavy rare earth elements and yttrium, whose D values decrease markedly with increasing pressure and majorite component. The effect on the lighter REE (e.g. Nd) is less pronounced, with D values slightly higher than are those for lower-pressure garnets; a similarly small effect on Sc is shown by its slightly lower D values than at lower pressure. D values for Zr and Hf show essentially no change compared both to lower- and higher-pressure garnets. Application of the lattice-strain model for element partitioning shows that there are mismatches between recently proposed predictive relationships using this model for partitioning of trivalent cations in garnet and garnets that exhibit the transformation to majorite. These mismatches are largely due to the structural changes attendant upon the majorite transformation with increasing pressure, and possibly on coexisting melt composition, because other parameters (temperature, bulk composition) have very narrow ranges in our experiments. Our results do provide, however, very good fits to the lattice-strain model that allow the calculation of D values for any trivalent cation entering the X site of the majoritic garnet crystal structure, at pressures from 5 to 9 GPa and in the presence of ultramafic silicate melt. Using these D values for fractionation of an assemblage containing majoritic garnet from a chondritic liquid, we show the very different signatures imparted by lower-pressure vs. higher-pressure garnets on important geochemical features such as REE patterns. These new data support the hypothesis that superchondritic CaO/Al (sub 2) O (sub 3) in martian meteorites is the result of garnet-majorite fractionation or partial melting in the garnet-majorite stability field in the martian mantle.

Mean HCN and CH sub(3)CN mixing ratios of 243 plus or minus 118 (median 218) ppt and 149 plus or minus 56 (median 138) ppt, respectively, were measured. These in situ observations correspond to a mean tropospheric HCN column of 4.2 x 10 super(15) molecules cm super(-2) and a CH sub(3)CN column of 2.5 x 10 super(15) molecules cm super(-2). This is in good agreement with the 0-12 km HCN column of 4.4 ( plus or minus 0.6) x 10 super(15) molecules cm super(-2) derived from infrared solar spectroscopic observations over Japan. Mixing ratios of HCN and CH sub(3)CN were greatly enhanced in pollution outflow from Asia and were well correlated with each other as well as with known tracers of biomass combustion (e.g. CH sub(3)Cl, CO). Volumetric enhancement (or emission) ratios (ERs) relative to CO in free tropospheric plumes, likely originating from fires, were 0.34% for HCN and 0.17% for CH sub(3)CN. ERs with respect to CH sub(3)Cl and CO in selected biomass burning (BB) plumes in the free troposphere and in boundary layer pollution episodes are used to estimate a global BB source of 0.8 plus or minus 0.4 Tg (N) yr super(-1) for HCN and 0.4 plus or minus 0.1 Tg (N) yr super(-1) for CH sub(3)CN. In comparison, emissions from industry and fossil fuel combustion are quite small (<0.05 Tg (N) yr super(-1)). The vertical structure of HCN and CH sub(3)CN indicated reduced mixing ratios in the marine boundary layer (MBL). Using a simple box model, the observed gradients across the top of the MBL are used to derive an oceanic loss rate of 8.8 x 10 super(-15) g (N) cm super(-2) s super(-1) for HCN and 3.4 x 10 super(-15) g (N) cm super(-2) s super(-1) for CH sub(3)CN. An air-sea exchange model is used to conclude that this flux can be maintained if the oceans are undersaturated in HCN and CH sub(3)CN by 27% and 6%, respectively. These observations also correspond to an open ocean mean deposition velocity (v sub(d)) of 0.12 cm s super(-1) for HCN and 0.06 cm s super(-1) for CH sub(3)CN. It is inferred that oceanic loss is a dominant sink for these cyanides and that they deposit some 1.4 Tg (N) of nitrogen annually to the oceans. Assuming loss to the oceans and reaction with OH radicals as the major removal processes, a mean atmospheric residence time of 5.0 months for HCN and 6.6 months for CH sub(3)CN is calculated. A global budget analysis shows that the sources and sinks of HCN and CH sub(3)CN are roughly in balance but large uncertainties remain in part due to a lack of observational data from the atmosphere and the oceans. Pathways leading to the oceanic (and soil) degradation of these cyanides are poorly known but are expected to be biological in nature. JF - Journal of Geophysical Research. D.

Experiments to determine the relationship or A. pushchinoensis K1 super(T) to oxygen showed that it was capable of aerobic growth, but preferred to grow anaerobically. During aerobic growth, the redox indicator resazurin was reduced as a result of hydrogen gas production. The facultatively anaerobic nature of K1 super(T) was ascertained by cultivation in aerobic liquid medium, where growth began at the bottom of the tube. The anaerobic nature of K1 super(T) was also indicated by a negative catalase reaction. This work is submitted to correct the description of the species A. pushchinoensis from obligate anaerobe to aerotolerant anaerobe and to emend the description of the genus Anoxybacillus from obligate anaerobes or facultative anaerobes to aerotolerant anaerobes or facultative anaerobes.

Gram-negative vibrio-shaped cells were observed, which were 0.6-0.7x1.2-2.7 mu m in size, motile by a single polar flagellum and occurred singly, in pairs or as short spirilla. Growth was observed at 15-48 degree C (optimum, 37 degree C), >1-7% NaCl, w/v (optimum, 3%) and pH 8.0-10.0 (optimum, 9.5). The novel isolate is strictly alkaliphilic, requires a high concentration of carbonate in the growth medium and is obligately anaerobic and catalase-negative. As electron donors, strain MLF1 super(T) uses hydrogen, formate and ethanol. Sulfate, sulfite and thiosulfate (but not sulfur or nitrate) can be used as electron acceptors. The novel isolate is a lithoheterotroph and a facultative lithoautotroph that is able to grow on hydrogen without an organic source of carbon. Strain MLF1 super(T) is resistant to kanamycin and gentamicin, but sensitive to chloramphenicol and tetracycline. The DNA G+C content is 63.0 mol% (HPLC). DNA-DNA hybridization with the most closely related species, Desulfonatronum lacustre Z-7951 super(T), exhibited 51% homology. Also, the genome size (1.6x10 super(9) Da) and T sub(m) value of the genomic DNA (71 plus or minus 2 degree C) for strain MLF1 super(T) were significantly different from the genome size (2.1x10 super(9) Da) and T sub(m) value (63 plus or minus 2 degree C) for Desulfonatronum lacustre Z-7951 super(T). On the basis of physiological and molecular properties, the isolate was considered to be a novel species of the genus Desulfonatronum, for which the name Desulfonatronum thiodismutans sp. nov. is proposed (the type strain is MLF1 super(T)=ATCC BAA-395 super(T)=DSM 14708 super(T)).

Data is compared between a sector where dust was predominant and a sector where dust was less of an influence. Coincident with dust were higher mixing ratios of anthropogenic pollutants. HNO sub(3), SO sub(2), and CO were higher in the dust sector than the nondust sector by factors of 2.7, 6.2, and 1.5, respectively. The colocation of dust and pollution sources allowed for the uptake of NO sub(3) super(-) and nss-SO sub(4) super(=) on the coarse dust aerosols, increasing the mixing ratios of these particulates by factors of 5.7 and 2.6 on average. There was sufficient nss-SO sub(4) super(=) to take up all of the NH sub(4) super(+) present, with enough excess nss-SO sub(4) super(=) to also react with dust CaCO sub(3). This suggests that the enhanced NO sub(3) super(-) was not in fine mode NH sub(4)NO sub(3). Particulate NO sub(3) super(-) (p-NO sub(3) super(-)) constituted 54% of the total NO sub(3) super(-) (t-NO sub(3) super(-)) on average, reaching a maximum of 72% in the dust sector. In the nondust sector, p-NO sub(3) super(-) contributed 37% to t- NO sub(3) super(-), likely due to the abundance of sea salts there. In two other sectors where the influence of dust and sea salt were minimal, p-NO sub(3) super(-) accounted for <15% of t-NO sub(3) super(-). JF - Journal of Geophysical Research. D.

We studied movements of Black Vultures between communal roosts in Florida using mark-resight methods. We marked 416 Black Vultures with patagial tags at two communal roosts in Orange County, Florida. A total of 1,245 resightings of 226 individuals were recorded over a 3-year period. Black Vultures made one-way movements between communal roosts of up to 152 km, and two-way movements (i.e., birds left a site and subsequently returned) between communal roosts of up to 144 km. Patterns of resightings indicated that some Black Vultures use several roosts over wide geographic ranges during parts of their lives. Long distance exchanges between roosts and high nightly turnover of membership at roosts leads to concerns that control of nuisance Black Vulture roosts has the potential to impact nontarget populations in a geographic area well beyond a given communal roost.

The CO sub(2 )spatial distributions were notably influenced by cyclogenesis-triggered transport of regionally polluted continental air masses. Examination of the CO sub(2) to C sub(2)H sub(2)/CO ratio indicated rapid outflow of combustion-related emissions in the free troposphere below 8 km. Although the highest CO sub(2) mixing ratios were measured within the Pacific Rim region, enhancements were also observed further east over the open ocean at locations far removed from surface sources. Near the Asian continent, discrete plumes encountered within the planetary boundary layer contained up to 393 ppmv of CO sub(2). Coincident enhancements in the mixing ratios of C sub(2)Cl sub(4), C sub(2)H sub(2), and C sub(2)H sub(4) measured concurrently revealed combustion and industrial sources. To elucidate the source distributions of CO sub(2), an emissions database for Asia was examined in conjunction with the chemistry and 5-day backward trajectories that revealed the WNW/W sector of northeast Asia was a major contributor to these pollution events. Comparisons of NOAA/CMDL and JMA surface data with measurements obtained aloft showed a strong latitudinal gradient that peaked between 35 degree and 40 degree N. We estimated a net CO sub(2) flux from the Asian continent of approximately 13.93 Tg C day super(-1) for late winter/early spring with the majority of the export (79%) occurring in the lower free troposphere (2-8 km). The apportionment of the flux between anthropogenic and biospheric sources was estimated at 6.37 Tg C day super(-1) and 7.56 Tg C day super(-1), respectively. JF - Journal of Geophysical Research. D.

Remote measurements were made with an airborne lidar to provide O sub(3) and multiple-wavelength aerosol backscatter profiles from near the surface to above the tropopause along the flight track. In situ measurements of O sub(3), aerosols, and a wide range of trace gases were made onboard the DC-8. Five-day backward trajectories were used in conjunction with the O sub(3) and aerosol distributions on each flight to indicate the possible origin of observed air masses, such as from biomass burning regions, continental pollution, desert regions, and oceanic regions. Average latitudinal O sub(3) and aerosol scattering ratio distributions were derived from all flights west of 150 degree E, and these distributions showed the average latitude and altitude dependence of different dynamical and chemical processes in determining the atmospheric composition over the western Pacific. TRACE-P (TP) showed an increase in the average latitudinal distributions of both O sub(3) and aerosols compared to PEM-West B (PWB), which was conducted in February-March 1994. O sub(3), aerosol, and potential vorticity levels were used to identify nine air mass types and quantify their frequency of occurrence as a function of altitude. This paper discusses the characteristics of the different air mass types encountered during TP and compares them to PWB. These results confirmed that most of the O sub(3) increase in TP was due to photochemistry. The average latitudinal eastward O sub(3) flux in the western Pacific during TP was found to peak near 32 degree N with a total average O sub(3) flux between 14 and 46 degree N of 5.2 Tg/day. The eastward total CO flux was calculated to be 2.2 Tg-C/day with similar to 6% estimated from Asia. The Asian flux of CO sub(2) and CH sub(4) was estimated at 4.9 and 0.06 Tg-C/day.

Strain APO was mesophilic (range 10-48C, optimum of 37C); halophilic (NaCl range 1-20% (w/v) with optimum of 3-5% (w/v), and alkaliphilic (pH range 8.0-10.5, optimum 9.5). The novel isolate required sodium ions in the medium. Strain APO was an organotroph with a fermentative type of metabolism and used the substrates peptone, bacto-tryptone, casamino acid, yeast extract, l-serine, l-lysine, l-histidine, l-arginine, and pyruvate. The new isolate performed the Stickland reaction with the following amino acid pairs: proline + alanine, glycine + alanine, and tryptophan + valine. The main end product of growth was acetate. High activity of CO dehydrogenase and hydrogenase indicated the presence of a homoacetogenic, non-cycling acetyl-CoA pathway. Strain APO was resistant to kanamycin but sensitive to chloramphenicol, tetracycline, and gentamycin. The G+C content of the genomic DNA was 44.4mol% (by HPLC method). The sequence of the 16S rRNA gene of strain APO possessed 98.2% similarity with the sequence from Tindallia magadiensis Z-7934, but the DNA-DNA hybridization value between these organisms was only 55%. On the basis of these physiological and molecular properties, strain APO is proposed to be a novel species of the genus Tindallia with the name Tindallia californiensis sp. nov., (type strain APO = ATCC BAA-393 = DSM 14871).

AN - 73561397; 12974241 AB - We report a molecular modeling study to investigate the polymer-carbon black (CB) composite-analyte interactions in resistive sensors. These sensors comprise the JPL electronic nose (ENose) sensing array developed for monitoring breathing air in human habitats. The polymer in the composite is modeled based on its stereoisomerism and sequence isomerism, while the CB is modeled as uncharged naphthalene rings with no hydrogens. The Dreiding 2.21 force field is used for the polymer, solvent molecules and graphite parameters are assigned to the carbon black atoms. A combination of molecular mechanics (MM) and molecular dynamics (NPT-MD and NVT-MD) techniques are used to obtain the equilibrium composite structure by inserting naphthalene rings in the polymer matrix. Polymers considered for this work include poly(4-vinylphenol), polyethylene oxide, and ethyl cellulose. Analytes studied are representative of both inorganic and organic compounds. The results are analyzed for the composite microstructure by calculating the radial distribution profiles as well as for the sensor response by predicting the interaction energies of the analytes with the composites. c2003 Elsevier Science B.V.

AN - 71406960; 14649254 AB - The paper considers problems of biosynthesis of higher plants' biomass and "biological incineration" of plant wastes in a working physical model of biological LSS. The plant wastes are "biologically incinerated" in a special heterotrophic block involving Californian worms, mushrooms and straw. The block processes plant wastes (straw, haulms) to produce soil-like substrate (SLS) on which plants (wheat, radish) are grown. Gas exchange in such a system consists of respiratory gas exchange of SLS and photosynthesis and respiration of plants. Specifics of gas exchange dynamics of high plants--SLS complex has been considered. Relationship between such a gas exchange and PAR irradiance and age of plants has been established. Nitrogen and iron were found to the first to limit plants' growth on SLS when process conditions are deranged. The SLS microflora has been found to have different kinds of ammonifying and denitrifying bacteria which is indicative of intensive transformation of nitrogen-containing compounds. The number of physiological groups of microorganisms in SLS was, on the whole, steady. As a result, organic substances--products of exchange of plants and microorganisms were not accumulated in the medium, but mineralized and assimilated by the biocenosis. Experiments showed that the developed model of a man-made ecosystem realized complete utilization of plant wastes and involved them into the intrasystem turnover. c2003 International Astronautical Federation.

AN - 71316759; 14584511 AB - The ability to monitor air contaminants in the shuttle and the International Space Station is important to ensure the health and safety of astronauts, and equipment integrity. Three specific space applications have been identified that would benefit from a chemical monitor: (a) organic contaminants in space cabin air; (b) hypergolic propellant contaminants in the shuttle airlock; (c) pre-combustion signature vapors from electrical fires. NASA at Kennedy Space Center (KSC) is assessing several commercial and developing electronic noses (E-noses) for these applications. A short series of tests identified those E-noses that exhibited sufficient sensitivity to the vapors of interest. Only two E-noses exhibited sufficient sensitivity for hypergolic fuels at the required levels, while several commercial E-noses showed sufficient sensitivity of common organic vapors. These E-noses were subjected to further tests to assess their ability to identify vapors. Development and testing of E-nose models using vendor supplied software packages correctly identified vapors with an accuracy of 70-90%. In-house software improvements increased the identification rates between 90 and 100%. Further software enhancements are under development. Details on the experimental setup, test protocols, and results on E-nose performance are presented in this paper along with special emphasis on specific software enhancements. c2003 Elsevier Science B.V.

The prospects and limitations of using the V content of peridotites as a proxy for paleo-fO (sub 2) at the time of melt extraction were investigated here by assessing the uncertainties in V measurements and the sensitivity of V as a function of degree of melt extracted and fO (sub 2) . V-MgO and V-Al (sub 2) O (sub 3) systematics were found to be sensitive to fO (sub 2) variations, but consideration of the uncertainties in measurements and model parameters indicates that V is sensitive only to relative fO (sub 2) differences greater than approximately 2 log units. Post-Archean oceanic mantle peridotites, as represented by abyssal peridotites and obducted massif peridotites, have V-MgO and -Al (sub 2) O (sub 3) systematics that can be modeled by 1.5 GPa melting between FMQ-3 and FMQ-1. This is consistent with fO (sub 2) 's of the mantle source for mid-ocean ridge basalts (MORBs) as determined by the Fe (super 3+) activity of peridotitic minerals and basaltic glasses. Some arc-related peridotites have slightly lower V for a given degree of melting than oceanic mantle peridotites, and can be modeled by 1.5 GPa melting at fO (sub 2) 's as high as FMQ. However, the majority of arc-related peridotites have V-MgO systematics overlapping that of oceanic mantle peridotites, suggesting that although some arc mantle may melt under slightly oxidizing conditions, most arc mantle does not. The fact that thermobarometrically determined fO (sub 2) 's in arc peridotites and lavas can be significantly higher than that inferred from V systematics, suggests that V retains a record of the fO (sub 2) during partial melting, whereas the activity of Fe (super 3+) in arc peridotitic minerals and lavas reflect subsequent metasomatic overprints and magmatic differentiation/emplacement processes, respectively. Peridotites associated with middle to late Archean cratonic mantle are characterized by highly variable V-MgO systematics. Tanzanian cratonic peridotites have V systematics indistinguishable from post-Archean oceanic mantle and can be modeled by 3 GPa partial melting at approximately FMQ-3. In contrast, many South African and Siberian cratonic peridotites have much lower V contents for a given degree of melting, suggesting at first glance that partial melting occurred at high fO (sub 2) 's. More likely, however, their unusually low V contents for a given degree of melting may be artifacts of excess orthopyroxene, a feature that pervades many South African and Siberian peridotites but not the Tanzanian peridotites. This is indicated by the fact that the V contents of South African and Siberian peridotites are correlated with increases in SiO (sub 2) content, generating data arrays that cannot be modeled by partial melting but can instead be generated by the addition of orthopyroxene through processes unrelated to primary melt depletion. Correction for orthopyroxene addition suggests that the South African and Siberian peridotites have V-MgO systematics similar to those of Tanzanian peridotites. Thus, if the Tanzanian peridotites represent the original partial melting residues, and if the South African and Siberian peridotites have been modified by orthopyroxene addition, then there is no indication that Archean cratonic mantle formed under fO (sub 2) 's significantly greater than that of modern oceanic mantle. Instead, the fO (sub 2) 's inferred from the V systematics in these three cratonic peridotite suites are within range of modern oceanic mantle. This also suggests that the transition from a highly reducing mantle in equilibrium with a metallic core to the present oxidized state must have occurred by late Archean times.

These simulations aim to quantify the impact of realistic snow conditions on skill in the GCMs. In this study, ensemble climate simulations conducted for Northern Hemisphere spring (March-June) that span the years 1982-1998 are considered. For each year of these seasonal simulations, a pair of complementary runs is performed. For one of the simulations, snow conditions are allowed to evolve interactively; for the other simulation, the snow conditions are prescribed, according to a daily, global snow depth analysis, within each of the land modules of the GCMs. For this study, the impact of snow conditions on simulated near-surface air temperature is assessed. The results indicate that the prescribed (and presumably improved) snow conditions in the GCMs play a beneficial role in skillfully capturing the observed spatial/temporal patterns of interannual variations of near-surface air temperature, at a local scale. Through consideration of the surface energy- budget and the effect of snow cover on surface albedo, the localized improvement of near-surface air temperature skill (both in the spatial correlations and in the root-mean-square error) that results from the prescribed snowfields is found to be strongly tied to when and where the interannual variabilities of snow cover and mean incident short wave radiation coincide. This impact of prescribed snow is also most considerable during the widespread ablation of the matured winter season snow cover, which typically occurs during April over the Northern Hemisphere. Overall, the impact of the prescribed snow over all land points (i.e. local and nonlocal) shows mixed results in its effect on near-surface air temperature skill. These mixed results most likely underscore the difficulty of the GCMs to consistently translate the localized skillful response into nonlocal/remote skill. In the end, physical parameterizations in GCMs should be improved before all seasonal prediction enhancements from improved snow conditions can be realized. JF - Journal of Geophysical Research. D.

Alterations that occur as SOM decays and is stabilized have proved difficult to study owing largely to its diverse initial chemical composition and stable isotope values. We examined SOM stable isotope ratios in relation to composition using solid-state super(13)C Cross Polarization Magic Angle Spin (CPMAS) nuclear magnetic resonance (NMR) in sequentially deeper organic and mineral horizon soil samples collected from an unpolluted ecosystem in southeast Alaska, USA, dominated by C sub(3) vegetation. We found that, as humified carbon (C not respired as CO sub(2) during decomposition) increased in aliphaticity (ratio of unsubstituted aliphatics to carbohydrates), it also increased in super(15)N but showed no clear trend in super(13)C. These results imply that humification (and the concomitant stabilization of soil C) at our site resulted from microbial alteration of organics rather than from accumulation of recalcitrant compounds. The strong, and previously unreported, relation between super(15)N and SOM composition found at our study site suggests that degree of SOM humification may be correlated with an increase in delta super(15)N SOM values relative to delta super(15)N for fresh litter and other source material.

However, less is known about the effects on ecosystems following fire, which include reduced productivity and changes in decomposition in the decade immediately following the disturbance. In this study, we assessed the impact of fire on net primary productivity (NPP) in the North American boreal forest using a 17-year record of satellite NDVI observations at 8- km spatial resolution together with a light-use efficiency model. We identified 61 fire scars in the satellite observations using digitized fire burn perimeters from a database of large fires. We studied the postfire response of NPP by analyzing the most impacted pixel within each burned area. NPP decreased in the year following the fire by 60-260 g C m super(-2) yr super(-1) (30-80%). By comparing pre- and postfire observations, we estimated a mean NPP recovery period for boreal forests of about 9 years, with substantial variability among fires. We incorporated this behavior into a carbon cycle model simulation to demonstrate these effects on net ecosystem production. The disturbance resulted in a release of C to the atmosphere during the first 8 years, followed by a small, but long-lived, sink lasting 150 years. Postfire net emissions were three times as large as from a model run without changing NPP. However, only small differences in the C cycle occurred between runs after 8 years due to the rapid recovery of NPP. We conclude by discussing the effects of fire on the long-term continental trends in satellite NDVI observed across boreal North America during the 1980s and 1990s.

The measurements cover a decade time span following the June 1991 Mount Pinatubo volcanic eruption and were recorded typically at 0.01 cm super(-1) spectral resolution. The measured HNO sub(3) stratospheric column shows a 20% decline from 9.16 x 10 super(15) molecules cm super(-2) from the first observation in March 1992 to 7.40 x 10 super(15) molecules cm super(-2) at the start of 1996 reaching a broad minimum of 6.95 x 10 super(15) molecules cm super(-2) thereafter. Normalized daytime NO and NO sub(2) stratospheric column trends for the full post-Pinatubo eruption time period equal (+1.56 plus or minus 0.45)% yr super(-1), 1 sigma, and (+0.52 plus or minus 0.32)% yr super(-1), 1 sigma, respectively. The long-term trends are superimposed on seasonal cycles with similar to 10% relative amplitudes with respect to mean values, winter maxima for HNO sub(3) and summer maxima for NO and NO sub(2). The measurements have been compared with two- dimensional model calculations utilizing version 6.1 Stratospheric Aerosol and Gas Experiment (SAGE) II sulfate aerosol surface area density measurements through 1999 and extended to the end of the time series by repeating the 1999 values. The model-calculated HNO sub(3), NO, and NO sub(2) stratospheric column time series agree with the measurements to within similar to 8% after taking into account the vertical sensitivity of the ground-based measurements. The consistency between the measured and model-calculated stratospheric time series confirms the decreased impact on stratospheric reactive nitrogen chemistry of the key heterogeneous reaction that converts reactive nitrogen to its less active reservoir form as the lower-stratospheric aerosol surface area density declined by a factor of similar to 20 after the eruption maximum.

AN - 85378695; pmid-12956587 AB - Most studies using the psychological refractory period (PRP) design suggest that dual-task performance is limited by a central bottleneck. Because subjects are usually told to emphasize Task 1, however, the bottleneck might reflect a strategic choice rather than a structural limitation. To evaluate the possibility that central operations can proceed in parallel, albeit with capacity limitations, we conducted two dual-task experiments with equal task emphasis. In both experiments, subjects tended to either group responses together or respond to one task well before the other. In addition, stimulus-response compatibility effects were roughly constant across stimulus onset asynchronies (SOAs). At the short SOA, compatibility effects also carried over onto response times for the other task. This pattern of results is difficult to reconcile with the possibility that subjects share capacity roughly equally between simultaneous central operations. However, this pattern is consistent with the existence of a structural central bottleneck.

AN - 73666564; 14503486 AB - The hormone-stimulated and growth-related cell surface hydroquinone (NADH) oxidase activity of etiolated hypocotyls of soybeans oscillates with a period of about 24 min or 60 times per 24-h day. Plasma membranes of soybean hypocotyls contain two such NADH oxidase activities that have been resolved by purification on concanavalin A columns. One in the apparent molecular weight range of 14-17 kDa is stimulated by the auxin herbicide 2,4-dichlorophenoxyacetic acid (2,4-D). The other is larger and unaffected by 2,4-D. The 2,4-D-stimulated activity absolutely requires 2,4-D for activity and exhibits a period length of about 24 min. Also exhibiting 24-min oscillations is the rate of cell enlargement induced by the addition of 2,4-D or the natural auxin indole-3-acetic acid (IAA). Immediately following 2,4-D or IAA addition, a very complex pattern of oscillations is frequently observed. However, after several hours a dominant 24-min period emerges at the expense of the constitutive activity. A recruitment process analogous to that exhibited by prions is postulated to explain this behavior. JF - In vitro cellular & developmental biology.

AN - 73474300; 12862332 AB - There is limited data about the long-term pulmonary effects of nitrox use in divers at shallow depths. This study examined changes in pulmonary function in a cohort of working divers breathing a 46% oxygen enriched mixture while diving at depths less than 12 m. A total of 43 working divers from the Neutral Buoyancy Laboratory (NBL), NASA-Johnson Space Center completed a questionnaire providing information on diving history prior to NBL employment, diving history outside the NBL since employment, and smoking history. Cumulative dive hours were obtained from the NBL dive-time database. Medical records were reviewed to obtain the diver's height, weight, and pulmonary function measurements from initial pre-dive, first year and third year annual medical examinations. The initial forced vital capacity (FVC) and forced expiratory volume in 1 s (FEV1) were greater than predicted, 104% and 102%, respectively. After 3 yr of diving at the NBL, both the FVC and FEV1 showed a significant (p < 0.01) increase of 6.3% and 5.5%, respectively. There were no significant changes in peak expiratory flow (PEF), forced mid-expiratory flow rate (FEF(25-75%)), and forced expiratory flow rates at 25%, 50%, and 75% of FVC expired (FEF25%, FEF50%, FEF75%). Cumulative NBL dive hours was the only contributing variable found to be significantly associated with both FVC and FEV1 at 1 and 3 yr. NBL divers initially belong to a select group with larger than predicted lung volumes. Regular diving with nitrox at shallow depths over a 3-yr period did not impair pulmonary function. Improvements in FVC and FEV1 were primarily due to a training effect.

AN - 73425547; 12839743 AB - Increasing soil nutrients through litter manipulation, pollution, or fertilization can adversely affect ectomycorrhizal (EM) communities by inhibiting fungal growth. In this study, we used molecular genetic methods to determine the effects of litter addition on the EM community of a Pinus contorta stand in Yellowstone National Park that regenerated after a stand-replacing fire. Two controls were used; in unmodified control plots nothing was added to the soil, and in perlite plots perlite, a chemically neutral substance, was added to maintain soil moisture and temperature at levels similar to those under litter. We found that (i) species richness did not change significantly following perlite addition (2.6 +/- 0.3 species/core in control plots, compared with 2.3 +/- 0.3 species/core in perlite plots) but decreased significantly (P < 0.05) following litter addition (1.8 +/- 0.3 species/core); (ii) EM infection was not affected by the addition of perlite but increased significantly (P < 0.001) in response to litter addition, and the increase occurred only in the upper soil layer, directly adjacent to the added litter; and (iii) Suillus granulatus, Wilcoxina mikolae, and agaricoid DD were the dominant organisms in controls, but the levels of W. mikolae and agaricoid DD decreased significantly in response to both perlite and litter addition. The relative levels of S. granulatus and a fourth fungus, Cortinariaceae species 2, increased significantly (P < 0.01 and P < 0.05, respectively) following litter addition. Thus, litter addition resulted in some negative effects that may be attributable to moisture-temperature relationships rather than to the increased nutrients associated with litter. Some species respond positively to litter addition, indicating that there are differences in their physiologies. Hence, changes in the EM community induced by litter accumulation also may affect ecosystem function.

To help further explain the relationship between snow cover, turbulent exchanges and runoff production, a simple equivalent model (SEM) was devised to reproduce the seasonal and annual fluxes simulated by 13 LSSs that participated in PILPS Phase 2(e). The design of the SEM relates the annual partitioning of precipitation and energy in the LSSs to three primary parameters: snow albedo, effective aerodynamic resistance and evaporation efficiency. Isolation of each of the parameters showed that the annual runoff production was most sensitive to the aerodynamic resistance. The SEM was somewhat successful in reproducing the observed LSS response to a decrease in shortwave radiation and changes in wind speed forcings. SEM parameters derived from the reduced shortwave forcings suggested that increased winter stability suppressed turbulent heat fluxes over snow. Because winter sensible heat fluxes were largely negative, reductions in winter shortwave radiation resulted in an increase in annual average sensible heat.

Atmospheric forcing data (precipitation, air temperature, specific humidity, wind speed, downward shortwave and longwave radiation) for a 20-year period (1979-1998) were provided to the 21 participating modeling groups for 218 1/4 degrees grid cells that represented the study domain. The first decade (1979-1988) of the period was used for model spin-up. The quality of meteorologic forcing variables is of particular concern in high-latitude experiments and the quality of the gridded dataset was assessed to the extent possible. The lack of sub-daily precipitation, underestimation of true precipitation and the necessity to estimate incoming solar radiation were the primary data concerns for this study. The results from two of the three types of runs are analyzed in this, the first of a three-part paper: (1) calibration-validation runs--calibration of model parameters using observed streamflow was allowed for two small catchments (570 and 1300 km (super 2) ), and parameters were then transferred to two other catchments of roughly similar size (2600 and 1500 km (super 2) ) to assess the ability of models to represent ungauged areas elsewhere; and 2) reruns--using revised forcing data (to resolve problems with apparent underestimation of solar radiation of approximately 36%, and certain other problems with surface wind in the original forcing data). Model results for the period 1989-1998 are used to evaluate the performance of the participating land-surface schemes in a context that allows exploration of their ability to capture key processes spatially. In general, the experiment demonstrated that many of the LSSs are able to capture the limitations imposed on annual latent heat by the small net radiation available in this high-latitude environment. Simulated annual average net radiation varied between 16 and 40 W/m (super 2) for the 21 models, and latent heat varied between 18 and 36 W/m (super 2) . Among-model differences in winter latent heat due to the treatment of aerodynamic resistance appear to be at least as important as those attributable to the treatment of canopy interception. In many models, the small annual net radiation forced negative sensible heat on average, which varied among the models between -11 and 9 W/m (super 2) . Even though the largest evaporation rates occur in the summer (June, July and August), model-predicted snow sublimation in winter has proportionately more influence on differences in annual runoff volume among the models. A calibration experiment for four small sub-catchments of the Torne-Kalix basin showed that model parameters that are typically adjusted during calibration, those that control storage of moisture in the soil column or on the land surface via ponding, influence the seasonal distribution of runoff, but have relatively little impact on annual runoff ratios. Similarly, there was no relationship between annual runoff ratios and the proportion of surface and subsurface discharge for the basin as a whole.

This experiment focuses on simulations of land-surface water and energy fluxes in the 58,000-km (super 2) Torne and Kalix river systems in northern Scandinavia, during the period 1989-1998. All models participating in PILPS Phase 2(e) capture the broad dynamics of snowmelt and runoff, but large differences in snow accumulation and ablation, turbulent heat fluxes, and streamflow exist. The greatest among-model differences in energy and moisture fluxes in these high-latitude environments occur during the spring snowmelt period, reflecting different model parameterizations of snow processes. Differences in net radiation are governed by differences in the simulated radiative surface temperature during the winter months and by differences in surface albedo during the spring/early summer. Differences in net radiation are smallest during the late summer when snow is absent. Although simulated snow sublimation is small for most models, a few models show annual snow sublimation of about 100 mm. These differences in snow sublimation appear to be largely dependent on differences in snow surface roughness parameterizations. The models with high sublimation generally lose their snowpacks too early compared to observations and underpredict the annual runoff. Differences in runoff parameterizations are reflected in differences in daily runoff statistics. Although most models show a greater variability in daily streamflow than the observations, the models with the greatest variability (as much as double the observed variability), produce most of their runoff through fast response, surface runoff mechanisms. As a group, those models that took advantage of an opportunity to calibrate to selected small catchments and to transfer calibration results to the basin at large had a smaller bias and root mean squared error (RMSE) in daily streamflow simulations compared with the models that did not calibrate.

However there is good evidence that early in it's history it had liquid water and possibly life. The main question in the future exploration of Mars is the search for an independent origin of life on that planet. Ecosystems in cold, dry locations on Earth, such as the Antarctic dry valleys, provide examples of how life on early Mars might have survived and where to look for fossils. Fossils are not enough. We will want to determine not only if life on Mars, but if that life was a separate genesis from life on Earth. For this determination we need to access intact martian life, possibly frozen in the deep old permafrost. It is possible that at some time in the future we might recreate habitable conditions on Mars, returning it to the life-bearing state it may have enjoyed early in its history. Our studies of Mars are still in a preliminary state but everything we have learned suggests that it may be possible to restore Mars to a habitable climate.

Here we show that if the age of the lake is such that the lake water mass has been cycled over 30 times then the total dissolved gas equilibrates at about 2.5 liters (STP) of gas per kg of water; high enough to have important implications for drilling into this deep subglacial lake.

However, use of these photoluminescent nanocrystals in bacteria has not previously been reported, and their large size (3 to 10 nm) makes it unclear whether they inhibit bacterial recognition of attached molecules and whether they are able to pass through bacterial cell walls. Here we describe the use of conjugated CdSe QDs for strain- and metabolism-specific microbial labeling in a wide variety of bacteria and fungi, and our analysis was geared toward using receptors for a conjugated biomolecule that are present and active on the organism's surface. While cell surface molecules, such as glycoproteins, make excellent targets for conjugated QDs, internal labeling is inconsistent and leads to large spectral shifts compared with the original fluorescence, suggesting that there is breakup or dissolution of the QDs. Transmission electron microscopy of whole mounts and thin sections confirmed that bacteria are able to extract Cd and Se from QDs in a fashion dependent upon the QD surface conjugate.

Here, it is demonstrated that while both the radiative heating by increasing CO2 and the resulting higher sea surface temperatures contribute to warm the atmosphere, they act against each other in changing the hydrological cycle. As a consequence, in a warmer climate forced by increasing CO2 the intensity of the hydrological cycle can be either more or less intense depending upon the degree of surface warming.

This study was conducted to evaluate patterns in an 18-year record of global satellite observations of vegetation phenology from the Advanced Very High Resolution Radiometer (AVHRR) as a means to characterize major ecosystem disturbance events and regimes. The fraction absorbed of photosynthetically active radiation (FPAR) by vegetation canopies worldwide has been computed at a monthly time interval from 1982 to 1999 and gridded at a spatial resolution of 0.5 degree latitude /longitude. Potential disturbance events of large extent (> 0.5 Mha) were identified in the FPAR time series by locating anomalously low values (FPAR-LO) that lasted longer than 12 consecutive months at any 0.5 degree pixel. We find that nearly 400 Mha of the global land surface could be identified with at least one FPAR-LO event over the 18-year time series. The majority of these potential disturbance events occurred in tropical savanna and shrublands or in boreal forest ecosystem classes. Verification of potential disturbance events from our FPAR-LO analysis was carried out using documented records of the timing of large-scale wildfires at locations throughout the world. Disturbance regimes were further characterized by association analysis with historical climate anomalies. Assuming accuracy of the FPAR satellite record to characterize major ecosystem disturbance events, we estimate that nearly 9 Pg of carbon could have been lost from the terrestrial biosphere to the atmosphere as a result of large-scale ecosystem disturbance over this 18-year time series.

AN - 85374013; pmid-12822790 AB - Background noise studies have been extended from air condenser microphones to piezoresistive, electret condenser, and ceramic microphones. Theoretical models of the respective noise sources within each microphone are developed and are used to derive analytical expressions for the noise power spectral density for each type. Several additional noise sources for the piezoresistive and electret microphones, beyond what had previously been considered, were applied to the models and were found to contribute significantly to the total noise power spectral density. Experimental background noise measurements were taken using an upgraded acoustic isolation vessel and data acquisition system, and the results were compared to the theoretically obtained expressions. The models were found to yield power spectral densities consistent with the experimental results. The measurements reveal that the 1/f noise coefficient is strongly correlated with the diaphragm damping resistance, irrespective of the detection technology, i.e., air condenser, piezoresistive, etc. This conclusion has profound implications upon the expected 1/f noise component of micromachined (MEMS) microphones.

AN - 73635039; 12959129 AB - The unique feature of the space radiation environment is the dominance of high-energy charged particles (HZE or high LET radiation) emitted by the Sun and galactic sources, or trapped in the Van Allen radiation belts. These charged particles present a significant hazard to space flight crews, and accelerator-based experiments are underway to quantify the health risks due to unavoidable radiation exposure. There are three principal properties of charged particles that distinguish them from conventional radiation, i.e. gamma rays and x-rays. First, they have a defined range in matter rather than an exponential absorption profile. Second, they undergo nuclear reactions to produce secondary particles. Third, and most important, they deposit their energy along well-defined linear paths or tracks rather than diffuse fields. The structured energy deposition pattern interacts on multiple scales with the biological structures of DNA, cells and tissues to produce correlated patterns of damage that evade repair systems. Traditional concepts of dose and its associated normalization parameter, RBE (relative biological effectiveness), break down under experimental scrutiny, and probabilistic models of risk based on the number of particle traversals per cell may be more appropriate. Unique patterns of DNA damage, gene expression, mobilization of repair proteins, activation of cytokines and remodeling of cellular microenvironment are observed following exposure to high LET radiation. At low levels of exposure the communication of bioactive substances from irradiated to unirradiated "bystander" cells can amplify the damage and cause a significant deviation from linearity in dose vs. response relations. Under some circumstances, there is even a multigenerational delay in the expression of radiation-induced genetic damage (genomic instability) which is not strictly dose dependent. These issues and the experimental evidence derived from ground based experiments at particle accelerators are presented along with speculation about how modified inertial conditions might perturb homeostatic responses to radiation to further complicate risk assessment for space flight.

AN - 73629725; 12959126 AB - NASA is developing the knowledge required to accurately predict and to efficiently manage radiation risk in space. The strategy employed has three research components: (1) ground-based simulation of space radiation components to develop a science-based understanding of radiation risk; (2) space-based measurements of the radiation environment on planetary surfaces and interplanetary space, as well as use of space platforms to validate predictions; and, (3) implementation of countermeasures to mitigate risk. NASA intends to significantly expand its support of ground-based radiation research in line with completion of the Booster Applications Facility at Brookhaven National Laboratory, expected in summer of 2003. A joint research solicitation with the Department of Energy is under way and other interagency collaborations are being considered. In addition, a Space Radiation Initiative has been submitted by the Administration to Congress that would provide answers to most questions related to the International Space Station within the next 10 years.

AN - 73628194; 12959125 AB - The goals of space radiation health research are to understand qualitatively and quantitatively the ionizing radiations present in the space environment, identify qualitatively and quantitatively the risks associated with these radiations, and discover countermeasures to mitigate these risks. The articles that follow address each of these three components of space radiation health research. This article introduces the basic science and definitions underlying radiation health research and protection. Space radiations consist of energetic protons from the sun, protons and electrons from the sun that are trapped in the Earth's magnetic field, and cosmic rays that include energetic nuclei of H, He, C, N, O and Fe atoms. The risks presented to space travelers by these radiations include cancer due to protons and cosmic-ray exposure, immune failure due to high-dose solar proton storms, and possible neurological effects caused by single tracks of cosmic-ray heavy nuclei. Potential countermeasures include shielding, medication consisting of radical scavengers, anti-oxidant consumption, cytokines, and cell transplants.

AN - 73625325; 12959130 AB - Exposure to the types of ionizing radiation encountered during space travel may cause a number of health-related problems, but the primary concern is related to the increased risk of cancer induction in astronauts. The major types of radiation considered to be of importance during space travel are protons and particles of high atomic number and high energy (HZE particles). It is now clear that biological countermeasures can be used to prevent or reduce the levels of biological consequences resulting from exposure to protons or HZE particles, including the induction of cancer, immunosuppression and neurological defects caused by these types of ionizing radiation. Research related to the dietary additions of agents to minimize the risks of developing health-related problems which can result from exposure to space radiations is reviewed.

AN - 73621735; 12959127 AB - Estimating the biological risks from space radiation remains a difficult problem because of the many radiation types including protons, heavy ions, and secondary neutrons, and the absence of epidemiology data for these radiation types. Developing useful biophysical parameters or models that relate energy deposition by space particles to the probabilities of biological outcomes is a complex problem. Physical measurements of space radiation include the absorbed dose, dose equivalent, and linear energy transfer (LET) spectra. In contrast to conventional dosimetric methods, models of radiation track structure provide descriptions of energy deposition events in biomolecules, cells, or tissues, which can be used to develop biophysical models of radiation risks. In this paper, we address the biophysical description of heavy particle tracks in the context of the interpretation of both space radiation dosimetry and radiobiology data, which may provide insights into new approaches to these problems.

AN - 73518344; 12897457 AB - Natural products involved in plant-plant and plant-microorganism ecological interaction (Allelochemicals) are an important potential source for alternative agrochemicals and pharmaceuticals, in order to solve the many problems derived from inadequate culture practices and abuse of synthetic herbicides. Isolation, structural determination, bioassay techniques and applicability for these compounds in crop protection and pharmaceutical research are discussed, and future trends on Allelochemicals applications are examined. The new strategies for sustainable ecosystems controlled by allelochemicals offer a particular interest for the development of human bases in space, since these products can stimulate or inhibit plant germination and growth, and permit to develop crops with low residue amounts in water, facilitating wastewater treatment and recycling.

AN - 73518297; 12897455 AB - We have studied on allelopathy of plants and developed methods to identify the effective substances in root exudates, leaf leacheate, and volatile chemicals emitted from plants. We found traditional cover plants that show allelopathic activity are useful for weed control. It could eliminate the use of synthetic chemicals for this purpose. Allelopathy is a natural power of plants to protect themselves by producing natural organic chemicals. Some endemic plants in Asia, already known by farmers in the region, as either cover crops used in intercropping, hedgerow, or agroforestry, were found to possess strong allelopathic abilities. Our group identified several allelochemicals from these plants. These allelopathic cover crops, mostly leguminous plants, provide protein rich food, and grow easily without artificial fertilizers, herbicides, insecticides and fungicides. In this regards, these allelopathic cover crops could save food shortage in rural area, and are useful for environmental conservation. Screenings of allelopathic plants by specific bioassays and field tests have been conducted. Hairy vetch (Vicia villosa) and Velvet bean (Mucuna pruriens) are two promising species for the practical application of allelopathy. An amino acid, L-DOPA, unusual in plants, plays an important role as allelochemical in Velvet bean (Mucuna pruriens). Hairy vetch is the most promising cover plant for the weed control in orchard, vegetable and rice production and even for landscape amendment in abandoned field in Japan. We have isolated "cyanamide", a well known nitrogen fertilizer, from Hairy vetch. This is the first finding of naturally produced cyanamide in the world.

The similar depletions have been used as evidence that the Moon inherited its mantle from the Earth after a giant impact event. We have conducted liquid metal-liquid silicate partitioning experiments for V, Cr, and Mn from 3 to 14 GPa and 1723 to 2573 K to understand the behavior of these elements during planetary core formation. Our experiments have included systematic studies of the effects of temperature, silicate composition, metallic S-content, metallic C-content, and pressure. Temperature has a significant effect on the partitioning of V, Cr, Mn, with all three elements increasing their partitioning into the metallic liquid with increasing temperature. In contrast, pressure is not observed to affect the partitioning behavior. The experimental results show the partitioning of Cr and Mn are hardly dependent on the silicate composition, whereas V partitions more strongly into depolymerized silicate melts. The addition of either S or C to the metallic liquid causes increased metal-silicate partition coefficients for all three elements. Parameterizing and applying the experimental data, we find that the Earth's mantle depletions of V, Cr, and possibly Mn can be explained by core formation in a high-temperature magma ocean under oxygen fugacity conditions about two log units below the iron-wustite buffer, though the depletion of Mn may be due entirely to its volatility. However, more oxidizing conditions proposed in recent core formation models for the Earth cannot account for any of the depletions. Additionally, because we observe no pressure effect on the partitioning behavior, the data do not require the mantle of the Moon to be derived from the Earth's mantle, although this is not ruled out. All that is required to create depletions of V, Cr, and Mn in a mantle is a planetary body that is hot enough and reducing enough during its core formation. Such conditions could have existed on the Moon-forming impactor.

We merge two enabling technologies, global models of Earth system processes and satellite derived chlorophyll concentrations to assess the importance of Fe in oceanic biogeochemistry. We present an objective correlation analysis to elucidate the spatial response of chlorophyll to iron flux considering the ocean surface meridional center of mass in areas with high correlation.

The usual approaches to estimating ET employ remote sensing observations and a surface energy flux model. However, resolution of remote sensing data, needed to observe patterns of biophysical variables, is commonly too coarse (>1 km) to distinguish between land cover types that constrain ET. Accuracy of ET estimates can be improved by using higher-resolution (<100 m) remote sensing data since they can distinguish clusters of vegetation from bare soil fields and water bodies. A demonstration of this potential is shown using aircraft-based remote sensing observations over a study site at El Reno, Oklahoma. Five midday surveys, conducted from 29 June to 2 July 1997, as part of the Southern Great Plains 1997 Experiment (SGP97), collected 12 m resolution images in the visible, near infrared, and thermal infrared. Surface temperature and vegetation density maps, created from these surveys, were combined with surface micrometeorological observations and with a two source energy balance model. Results from El Reno show that flux estimates with respect to ground- based eddy covariance observations can be accurate to within 40-80 W m super(-2). This means that the high spatial resolution observations can potentially produce ET estimates similar in quality to ground-based point measurements. Additional work, needed to show how high-resolution remote sensing estimates can be related to coarser resolution observations, is underway using the satellite sensors ASTER (15-90 m resolution) and MODIS (250 m to 1 km resolution).

However, advances in the spatial and spectral resolutions of sensors now available to ecologists are making the direct remote sensing of certain aspects of biodiversity increasingly feasible; for example, distinguishing species assemblages or even identifying species of individual trees. In cases where direct detection of individual organisms or assemblages is still beyond our grasp, indirect approaches offer valuable information about diversity patterns. Such approaches derive meaningful environmental parameters from biophysical characteristics that are revealed by remote sensing.

AN - 73409998; 12830828 AB - The electric field dependence of the mobilities of gas-phase protonated monomers [(MH+(H2O)n] and proton-bound dimers [M2H+(H2O)n] of organophosphorus compounds was determined at E/N values between 0 and 140 Td at ambient pressure in air with moisture between 0.1 and 15 000 ppm. Field dependence was described as alpha (E/N) and was obtained from the measurements of compensation voltage versus field amplitude in a planar high-field asymmetric waveform ion mobility spectrometer. The alpha function for protonated monomers to 140 Td was constant from 0.1 to 10 ppm moisture in air with onset of effect at approximately 50 ppm. The value of alpha increased 2-fold from 100 to 1000 ppm at all E/N values. At moisture values between 1000 and 10 000 ppm, a 2-fold or more increase in alpha (E/N) was observed. In a model proposed here, field dependence for mobility through changes in collision cross sections is governed by the degree of solvation of the protonated molecule by neutral molecules. The process of ion declustering at high E/N values was consistent with the kinetics of ion-neutral collisional periods, and the duty cycle of the waveform applied to the drift tube. Water was the principal neutral above 50 ppm moisture in air, and nitrogen was proposed as the principal neutral below 50 ppm. JF - The journal of physical chemistry.

AN - 36428084; 10083 AB - PURPOSE: The construction of a rail line between the Bayport Loop and the former Galveston, Houston, and Henderson Railroad (GH&H) line near Ellington Field in the vicinity of Houston in southeastern Harris County, Texas is proposed. The new rail line would be constructed by San Jacinto Rail Limited and operated by the Burlington Northern and Santa Fe Railway (BNSF), which now owns the former GH&H line. Seven alternatives, including a No Action Alternative and a No-Build Alternative, are considered in this draft EIS. Under the proposed action, the new rail line, which would extend 12.8 miles, would serve the petro-chemical industries in the Bayport Loop. Petro-chemical interests are now served solely by the Union Pacific Railroad (UP), limiting competition for rail service in the area. Implementation of the proposed action would result in rail operations to and from the new line over trackage rights on UP's GH&H line and UP's East Belt, Terminal, Lafayette, and Baytown Subdivision to the storage yard operted by CMC Railroad at Dayton, approximately 30 miles northeast of Houston. BNSF would run, on average, on train of approximately 36 to 66 cars per day in each direction. On an annual basis, a total of 13,000 to 24,000 carloads and an equal number of empty rail cars would operate on the proposed line, representing 28 to 51 percent of the rail traffic generated in the Bayport Loop. The majority of shipments would consist of non-hazardous plastic pellets transported in hopper cars. The remainder would consist of chemicals transported in tank cars. Currently, BNSF estimates that approximately 1,500 to 7,000 carloads of hazardous materials would be transported over the line per year. Other miscellaneous inbound and outbound commodities would also likely be transported. POSITIVE IMPACTS: The new rail line would provide competitive rail service to petro-chemical product shippers within the Bayport Loop. The new line would increase rail transport capacity and flexibility along the route. Constraints, including service disruptions, currently affecting rail shippers would be eliminated. The project would generate up to $80 million in construction-related expenditures. NEGATIVE IMPACTS: The increase in rail traffic along the line would increase emissions of noise and air pollutants somewhat. The rail line would cross nine jurisdictional surface water bodies and six non-jurisdictional drainage channels, resulting in habitat loss and increased levels of water pollutants in receiving waters. Approximately 2.84 acres of jurisdictional wetlands and 4.22 acres of non-jurisdictional wetlands would be affected. The rail line would fragment habitat and could affect the Texas prairie dawn, a federally protected endangered plant species. Transportation of hazardous materials would occur in an area populated by minority and low-income residents.

The new rail line would be constructed by San Jacinto Rail Limited and operated by the Burlington Northern and Santa Fe Railway (BNSF), which now owns the former GH&H line. Seven alternatives, including a No Action Alternative and a No-Build Alternative, are considered in this draft EIS. Under the proposed action, the new rail line, which would extend 12.8 miles, would serve the petro-chemical industries in the Bayport Loop. Petro-chemical interests are now served solely by the Union Pacific Railroad (UP), limiting competition for rail service in the area. Implementation of the proposed action would result in rail operations to and from the new line over trackage rights on UP's GH&H line and UP's East Belt, Terminal, Lafayette, and Baytown Subdivision to the storage yard operted by CMC Railroad at Dayton, approximately 30 miles northeast of Houston. BNSF would run, on average, on train of approximately 36 to 66 cars per day in each direction. On an annual basis, a total of 13,000 to 24,000 carloads and an equal number of empty rail cars would operate on the proposed line, representing 28 to 51 percent of the rail traffic generated in the Bayport Loop. The majority of shipments would consist of non-hazardous plastic pellets transported in hopper cars. The remainder would consist of chemicals transported in tank cars. Currently, BNSF estimates that approximately 1,500 to 7,000 carloads of hazardous materials would be transported over the line per year. Other miscellaneous inbound and outbound commodities would also likely be transported. POSITIVE IMPACTS: The new rail line would provide competitive rail service to petro-chemical product shippers within the Bayport Loop. The new line would increase rail transport capacity and flexibility along the route. Constraints, including service disruptions, currently affecting rail shippers would be eliminated. The project would generate up to $80 million in construction-related expenditures. NEGATIVE IMPACTS: The increase in rail traffic along the line would increase emissions of noise and air pollutants somewhat. The rail line would cross nine jurisdictional surface water bodies and six non-jurisdictional drainage channels, resulting in habitat loss and increased levels of water pollutants in receiving waters. Approximately 2.84 acres of jurisdictional wetlands and 4.22 acres of non-jurisdictional wetlands would be affected. The rail line would fragment habitat and could affect the Texas prairie dawn, a federally protected endangered plant species. Transportation of hazardous materials would occur in an area populated by minority and low-income residents.

AN - 75760619; 14552355 AB - As a direct consequence of exposure to microgravity astronauts experience a number of physiological changes, which can have serious medical implications when they return to Earth. Most immediate and significant are the head-ward shift of body fluids and the removal of gravitational loading from bone and muscles, which lead to progressive changes in the cardiovascular and musculoskeletal systems. Cardiovascular adaptations result in an increased incidence of orthostatic intolerance (fainting) post-flight, decreased cardiac output and reduced exercise capacity. Changes in the musculoskeletal system contribute significantly to the impaired functions experienced in the post-flight period. The underlying factor producing these changes is the absence of gravity. Countermeasures, therefore, are designed primarily to simulate Earth-like movements, stresses and system interactions. Exercise is one approach that has received wide operational use and acceptance in both the US and Russian space programmes, and has enabled humans to stay relatively healthy in space for well over a year. Although it remains the most effective countermeasure currently available, significant physiological degradation still occurs. The development of other countermeasures will therefore be necessary for longer duration missions, such as the human exploration of Mars.

AN - 73357625; 12790638 AB - The effects of cold plasma on Deinococcus radiodurans, plasmid DNA, and model proteins were assessed using microbiological, spectrometric, and biochemical techniques. In low power O(2) plasma (approximately 25 W, approximately 45 mTorr, 90 min), D. radiodurans, a radiation-resistant bacterium, showed a 99.999% reduction in bioburden. In higher power O(2) plasma (100 W and 500 mTorr), the reduction rate increased about 10-fold and observation by atomic force microscopy showed significant damage to the cell. Damage to cellular lipids, proteins, and chromosome was indicated by losses of infrared spectroscopic peaks at 2930, 1651, 1538, and 1245 cm(-1), respectively. In vitro experiments show that O(2) plasmas induce DNA strand scissions and cross-linking as well as reduction of enzyme activity. The observed degradation and removal of biomolecules was power-dependent. Exposures to 200 W at 500 mTorr removed biomolecules to below detection limits in 60 s. Emission spectroscopy indicated that D. radiodurans cells were volatilized into CO(2), CO, N(2), and H(2)O, confirming that these plasmas were removing complex biological matter from surfaces. A CO(2) plasma was not as effective as the O(2) plasma, indicating the importance of plasma composition and the dominant role of chemical degradation. Together, these findings have implications for NASA planetary protection schemes and for the contamination of Mars.

Mantle xenoliths from the subcontinental lithospheric mantle (SCLM) underlying these crustal blocks were entrained in Cenozoic basalts and brought to the surface. The Os isotopic compositions of these xenoliths are quite variable. The most refractory xenoliths (Al (sub 2) O (sub 3) <1.2 wt.%) from both blocks yield model Os T (sub RD) ages between 1.2 and 0.4 Ga. For the XMOB, this indicates that some portions of the underlying SCLM are approximately the same age as the overlying continental crust. This is typical of the age relations between SCLM and the overlying crust for most cratons. The refractory xenoliths with minimally depleted (super 187) Os/ (super 188) Os, however, suggest the addition of much younger, Phanerozoic lithospheric mantle. The lack of any xenoliths with Archean model ages in the SCLM underlying the NCC, sampled by this study, suggests that the original SCLM underlying the NCC block has been largely removed. This may have occurred during the Proterozoic, the Phanerozoic, or during both periods. These results highlight the complex age structure in the current SCLM beneath northeastern China, with lithosphere ranging in age from Proterozoic to additions within the past several 100 Ma.

The associated ophiolitic blocks belong to the Main Uralian Fault (MUF) melange zone considered to represent obducted early Palaeozoic oceanic crust. Despite their close geographical proximity, the two ore bodies are morphologically, mineralogically and isotopically quite different. Sulphides from Ivanovka possess higher Ni and Os and lower Re and Cu relative to those from Dergamish. The Re and Os isotope data for Dergamish define a best-fit line corresponding to a Late Devonian age of 366+ or -2 Ma (2sigma ) with an MSWD of 4.6. This age is some 40 My younger than the inferred Silurian crystallisation age of the associated mafic-ultramafic rocks, but in good agreement with the previously published Rb-Sr and Ar-Ar ages of 360-380 Ma corresponding to the high-pressure metamorphic age of the adjacent Maksyutov metamorphic complex. These data suggest that Re-Os systematics of the Dergamish sulphide deposit were reset, either by diffusion or recrystallisation, during high-pressure metamorphism or subsequent cooling. The preservation of unradiogenic Os isotopic ratios in some of the Ivanovka samples and the near chondritic initial Os isotopic composition obtained for the Dergamish samples indicates that most of the Os in the massive sulphides was ultimately derived from the mantle. The corresponding tectonic setting equates to an area with submarine high-level mantle rocks. In contrast, sulphides from Ivanovka have experienced continued re-equilibration and have been modified by post-depositional processes at least some of which occurred relatively recently.

The age of the Marie Byrd Land lithosphere is not known, as the only lower crustal samples (granulite and pyroxenite xenoliths) have proven resistant to conventional radiogenic dating methods. The oldest exposed magmatic rocks are Cambrian, and any Precambrian history for Marie Byrd Land, while speculated upon, is unknown. Here we present the first geochemical data for a peridotite xenolith suite from Marie Byrd Land, including Re-Os isotope measurements for 17 samples. The 17 spinel peridotites are from three volcanic centers: Mt Hampton and Mt Cumming, in the Executive Committee Range, and Mt Aldaz, in the USAS Escarpment. The xenoliths are residual lherzolites and harzburgites, ranging from fertile to depleted (e.g. 0.39-3.38 wt.% CaO) compositions. Re-Os isotopic systematics indicate a complex evolution for the Marie Byrd Land lithosphere. One sample records Re+Cu+ or -Os enrichment and two samples document localized Os enrichment, which is most likely related to supra-subduction zone processing, although enrichment due to plume interaction cannot be ruled out. Proterozoic lithosphere stabilization model ages of ca. 1.1 and >1.3 Ga are recorded in xenoliths from the Executive Committee Range. The Proterozoic ages are significantly older than outcropping mid-crustal rocks, marking Marie Byrd Land as a third circum-Pacific Phanerozoic mobile belt with preserved Proterozoic lithospheric mantle. The Mesoproterozoic Os model ages are consistent with Proterozoic Nd model ages in Marie Byrd Land granites and orthogneisses, and with a significant detrital zircon age component (ca. 1.0-1.2 Ga) in the thick Swanson Formation sediments that are exposed along the coast. The simplest interpretation of the available mantle and crustal age data is that the lower crust beneath Marie Byrd Land is also Proterozoic in age. Alternatively, if the mantle and lower crust in Marie Byrd Land are not temporally coupled, possible origins for the Proterozoic mantle include older lithosphere impinging from the adjacent East Antarctic craton, or lithospheric mantle that was incorporated into younger oceanic lithosphere during "messy" continental breakup (e.g. within an oceanic plateau) and subsequently accreted to the Antarctic margin.

Rhenium is strongly positively correlated with Yb for all these submarine basaltic glasses. Enriched (E-) and normal (N-) MORB as well as King's Triple Junction samples show similar correlations with constant Yb/Re ratios, indicating that Re and Yb exhibit similar compatibility during melt evolution [Chem. Geol. 139 (1997) 185]. In contrast, samples from the East and Central Lau Spreading Centers have much higher ratios compared with MORB samples and form steeper arrays on Re-Yb variation diagrams, similar to komatiites. More incompatible element-depleted samples including those from the Lau and Woodlark Basin spreading centers and the more depleted (D-) MORB samples are also distinguished from E- and N-MORB and samples from King's Triple Junction and Coriolis Troughs Basin on the basis of their higher Cu/Re ratios. These observed elemental systematics are interpreted to reflect progressive melting of depleted mantle, where previous melting events result in the elimination of sulfides in the source regions of the depleted samples.Using the determined Yb/Re and Ce/Mo ratios and assuming that the abundances of Yb and Ce are 10% and 40% reduced in the DMM compared to the primitive mantle (PM), average concentrations of 0.12 ppb for Re and 34 ppb for Mo are estimated for the DMM. The partition coefficients of the analysed moderately incompatible elements are in the order of Mo or = approximately 1 ppb, and low (super 187) Re/ (super 188) Os ratios (ranging between 0.4 and 2.4). The Re-Os isotope results for whole-rock komatiites and chromite separates yield a model 3 isochron age of 2762+ or -76 Ma. This age is in general agreement with previously determined U-Pb ages of zircons from associated felsic units and also with Sm-Nd and Pb-Pb isochron ages of these flows. This suite of Alexo komatiites, thus, demonstrates relatively limited mobility of Re and Os at the whole-rock scale, even after large-scale alteration and ambient lower greenschist facies metamorphism. The initial Os isotopic composition ( (super 187) Os/ (super 188) Os (sub (I)) = 0.1080+ or -0.0012) obtained from the regression is essentially chondritic (gamma (sub Os) = -0.1+ or -1.0). Our results, therefore, suggest an absence of any large-scale deviation in initial Os isotopic composition of the mantle source of these komatiites relative to the putative chondritic composition of the contemporaneous convective upper mantle. For these komatiites, Os was moderately compatible with the mantle residue (D (sub Os) (super mantle-melt) approximately 2.1), whereas Re was incompatible (D (sub Re) approximately 0.20). These D's are consistent with those previously estimated for other Archean komatiites. The apparent D (sub Os) (super olivine/liquid) and D (sub Re) (super olivine/liquid) in Alexo komatiites are 1.7 and 0.66, respectively. Our results, therefore, suggest that Os is slightly compatible, whereas Re is moderately incompatible in olivine or a coprecipitating phase during magmatic differentiation of komatiitic liquids. The concentrations of Re and Os in Alexo komatiites are also comparable to those reported for komatiites from other greenstone belts. The apparent magmatic behaviors of both Re and Os in the whole-rock komatiites indicate that the Re-Os elemental systematics are primary features of these rocks. The Os isotopic results obtained for the Alexo komatiites, combined with those from the spatially associated Munro Township komatiites suggest a source for komatiites in the southern volcanic zone of the Abitibi greenstone belt that was dominated by Os with a chondritic isotopic composition. Also, the Os isotopic results, combined with previous Nd and Pb isotopic results, are consistent with derivation of the komatiites from either the contemporaneous convective upper mantle or a deep mantle source with isotopically similar characteristics. These results imply that if the chondritic Os isotopic composition of the mantle sources for the komatiites were set by a chondritic "late veneer", most late accretion and subsequent homogenization within the mantle must have occurred prior to their eruption at approximately 2.7 Ga.

Os and Re concentrations vary from 0.02 to 8.2 and 0.003 to 0.437 ppb, respectively, and (super 187) Re/ (super 188) Os varies from 0.004 to 3.811. (super 187) Os/ (super 188) Os ratios range from 0.1226 to 0.1566. Regional variations in Re-Os isotope signatures are apparent, with peridotites from Avachinsky exhibiting the least radiogenic Os isotope signatures and lowest Re/Os ratios, and those from Bakening the most radiogenic Os and highest Re/Os. Peridotites from Valovayam span the distinct compositional fields defined by the Avachinsky and Bakening peridotites. All of the Kamchatka peridotites are, however, characterized by radiogenic (super 187) Os/ (super 188) Os compared to non-arc continental peridotites with comparable Re abundances or Re/Os ratios.The relatively radiogenic Os isotope signatures in the Kamchatka peridotites cannot easily be explained by contamination of the xenoliths by their host lavas, as this process would result in Re/Os ratios higher than observed in the xenoliths. In situ radiogenic ingrowth of high Re/Os mantle followed by recent Re depletion also cannot explain the observed radiogenic Os signatures in the Kamchatka peridotites, as the time required for radiogenic ingrowth would be significantly greater than the age of the lithospheric terranes that make up the respective regions of Kamchatka. The radiogenic Os isotope signatures in the Kamchatka peridotites are instead attributed to metasomatism of the Kamchatka sub-arc mantle wedge by radiogenic slab-derived fluids and melts. The regional variations in Re-Os isotope signatures are consistent with previous petrographic and geochemical studies of the Kamchatka mantle xenoliths that reveal multistage metasomatic histories resulting from interaction of the mantle wedge with a variety of slab-derived fluids and melts, including silicic slab-melt metasomatism associated with subduction of relatively hot, young ( approximately 15-25 Ma) oceanic crust in the northern arc front, hydrous slab-fluid metasomatism associated with subduction of colder, old ( approximately 100 Ma) oceanic crust in the southern arc front, and carbonate-rich slab-melt metasomatism in the southern segment behind the arc front, where the slab is deeper.Positive correlations between (super 187) Os/ (super 188) Os, La/Sm, and Ru/Ir in Avachinsky harzburgites support a model in which high f (sub O (sub 2) ) , Cl-rich, hydrous slab fluids transport LREE, Ru, and radiogenic Os into the mantle wedge beneath the southern arc front. Re is either not transported, or is not retained in the mantle during fluid-mantle interaction. Relatively higher Re and more radiogenic Os (but low Os abundances) in the Valovayam and Bakening peridotites indicate that both scavenging of mantle Os as well as exchange with radiogenic slab-derived Os, and incorporation of Re, occurs during interaction of the mantle wedge with oxidized, adakitic, and carbonate-rich slab melts. Similar ranges of Re-Os isotope signatures in peridotites from Avachinsky, Japan and Lihir, and from Valovayam and the Cascades, respectively, suggest that the age (temperature) and depth of subducting oceanic crust influences the Re-Os composition of metasomatized sub-arc mantle.

The proof of extant (super 99) Tc in the solar system would also tightly constrain the time interval between production of the nuclide and injection of s-process isotopes into the protosolar cloud. High-precision Ru isotopic data for group IIAB (Negrillos, Bennett County, Coahuila, Filomena, Old Woman) and IIIAB (Casas Grandes, Costilla Peak) iron meteorites, and the chondrites Allende (CV3) and Allegan (H5) indicate that the isotopic compositions of (super 98) Ru and (super 99) Ru in these meteorites overlap with the terrestrial values at the + or -0.8 and + or -0.3epsilon levels (parts in 10,000), respectively. Previous reports of positive deviations of (super 98) Ru in Negrillos and Casas Grandes likely reflect inaccurate measurements. Evaluation of processes that may fractionate Tc/Ru in solar system objects suggests that this ratio likely varied by only a factor of 2 or less. Using this constraint and solar system initial abundances of (super 99) Tc derived from astrophysical models, evolution models for the (super 99) Tc- (super 99) Ru system predict deviations in (super 99) Ru of >0.3epsilon only, if these fractionation events occurred during collapse of the molecular cloud (<10 ka). Thus, positive identification of enriched (super 99) Ru may require better than 0.1epsilon unit resolution. Absence of resolvable (super 98) Ru deviations indicates (super 98) Tc/ (super 96) Ru (sub .i) <2X10 (super -5) .

The heterogeneity of LREE patterns, in combination with widely scattering epsilon Nd[T = 3.81 Ga] values between -3.7 and +12.4, indicate that the REE systematics of the samples were disturbed by one (or more) metamorphic events which took place some considerable time after the original crystallization of the Isua belt. Furthermore, LREE-rich metasomatic fluids associated with the emplacement of tonalites into the supracrustals may have significantly altered the primary trace element budget. Extreme variations in whole rock gamma Os[T = 3.81 Ga] values of these rocks ranging from -8500 to +9 are favorably interpreted to derive from Re-additions during fluid hydrothermal alterations accompanying the early and late Archean metamorphic events. In contrast, the Re-Os isotope system remained intact in ultramafic-hosted chromites from Isua and from the Ujaragssuit nunat area about 20 km SE of the ISB. An average gamma Os[T = 3.81 Ga] value of +1.3+ or -2.5 (2sigma ) for the chromite population covers the entire range defined by the chondritic average, the convecting primitive upper mantle (PUM) [Nature 383 (1996) 517; Geochim. Cosmochim. Acta 65 (2001) 1311] and models involving outer core entrainment at this time. Given the uncertainty in the origin of the ultramafic rocks and, thus, the chromites, and the very high degree of alteration of these rocks within the ISB, our data do not conclusively allow to further impinge on the petrogenesis of the ISB mantle-derived rocks. Our data are the first though to vaguely hint at an early Archean mantle with a possible slightly suprachondritic initial (super 187) Os/ (super 188) Os isotopic composition. Similarities of unaltered pillow basalts with Phanerozoic boninites [Chem. Geol. 184 (2002) 231] may indicate a formation in an intra-oceanic subduction zone like geodynamic process, in which extreme early (Hadean?) depletion of a mantle source by melt extraction was followed by a second stage of melting induced by enriched subduction components. Alternatively, core-mantle interaction as a plausible mechanism for possible weak (super 187) Os enrichments in these rocks remains a valid hypothesis.

The bulk rock Ir concentrations range from 0.23 to 9.07 ng/g (total PGE contents range between 43.2 ng/g), exceeding the range previously found in mantle rocks. Two pyroxenite samples show large variabilities in their PGE concentrations, with Ir contents of 0.23 and 4.30 ng/g. No systematic dependence of the contents of PGE on the degree of fertility of the host rock was found.Three harzburgitic samples (1343, 589, 211) with significantly higher concentrations of all PGE in comparison to samples of similar fertility reflect the mobility of these elements in a metasomatized mantle. Approximately unfractionated PGE patterns (with the exception of Re) of the enriched samples indicate that the PGE were apparently transported with a single phase. The Al (sub 2) O (sub 3) vs. (super 187) Os/ (super 188) Os correlation for Eifel xenoliths reported by Schmidt and Snow [Contrib. Mineral. Petrol. 143 (2002) 694] indicates that massive redistribution of Os must have occurred recently. The simultaneous enrichment of some samples in Os, As and light REE and other incompatible lithophile elements suggests a single S-, As- and PGE-containing phase that was responsible for the metasomatism.

The origin of the OJP is explored by examining platinum-group element (PGE: Ru, Rh, Pd, Ir, Pt) abundances in these basalts. On Makira, mid-ocean ridge basalts (MORBs) and ocean island basalts (OIBs) are occasionally intercalated within the stratigraphic sequence of the OJP--the (OIB)-type basalts could be representative of the plume tail sequence and the MORB-type flows may be an indication of heterogeneity within the OJP source. Partial melting models indicate that the MORB-type basalts were generated from a source dominated by upper mantle material. However, they suggest that the OJP basalts and the OIB-type basalts were not generated from an exclusively upper mantle source. Our illustrative modeling shows the range of PGE compositions in these plume-generated basalts are best generated from a hybrid source that incorporates 0-0.5 wt.% of outer core material, 50% depleted upper mantle and 50-49.5% lower (primitive) mantle.

The analysed samples are divided into three groups based on their Mg-contents, high-Mg tholeiites (10-14 wt.% MgO), composed of primitive olivine tholeiites and picrites, evolved olivine tholeiites (7-10 wt.% MgO) and evolved basalts (4-7 wt.% MgO) consisting of FeTi basalts, quartz tholeiites and alkaline basalts. The high-Mg tholeiites have a range of compositions between a relatively Cu-rich and Pd-poor (120 ppm Cu and 6 ppb Pd) end-member and a relatively Cu-poor and Pd-rich (74 ppm Cu and 17 ppb Pd) end-member. There is a positive correlation between the highly siderophile elements, whereas Cu and Pd correlate negatively between the Cu-rich primitive olivine tholeiite and the Cu-poor picrite end-member. Negative correlation between Cu and the PGEs cannot be reconciled in a model where the two end-members form by varying degrees of partial melting of a common source. The sub-primitive mantle Cu/Pd ratio of the picrite end-member ( approximately 4300) could indicate a strongly depleted mantle source, where Pd was efficiently retained in mantle sulphide, relative to Cu, during previous melt extraction episodes. In mantle melting models presented here, the picrite composition can be approximated by 25% melting of a mantle source that previously lost a normal MORB component (F approximately 15%). The olivine tholeiite end-member (Cu/Pd approximately 19000) can be approximated in mantle melting models by assuming derivation from a separate source, one slightly Cu-enriched source undergoing melting beneath a rift. Based on Cu and Pd variations, the majority of high-Mg tholeiites are interpreted to be mixtures between melts derived from highly depleted to slightly enriched sources, which is consistent with previous studies of Sr-Nd isotopic variations. The similar range in Cu/Pd ratios of the high-Mg tholeiites and the evolved olivine tholeiites could infer that the latter evolved from parental liquids similar to the high-Mg tholeiites under S-undersaturated conditions. Relatively high Pd and low Ir concentrations in the evolved olivine tholeiite samples ( approximately 7 wt.% MgO) indicate, too, that these magmas underwent S-undersaturated fractionation during which Pd accumulated in the melt whereas Ir was incorporated into the fractionating assemblage. This is in contrast to the group of evolved basalts with less than 7 wt.% MgO with low PGE contents and high Cu/Pd ratios that strongly suggest that these samples have experienced S-saturation. We propose a scenario for melt generation beneath the Icelandic rift zone, where picritic magma is generated from a highly depleted mantle, whereas primitive olivine tholeiite magma forms from the depleted as well as a Cu-enriched source. It is proposed that Cu-enriched mantle domains were exhausted at depth since their melting products are absent in the most depleted picrite derived from the uppermost part of the central melting region. The olivine tholeiites can be approximated by around 11-12% partial melting in a triangular melting regime beneath the Icelandic rift zone. The olivine tholeiites are interpreted to reflect efficient melt collection from the deepest and most distal parts of the melting triangle. In contrast, the picrite represent a high degree of melting (F approximately 25%) without incorporation of melt batches from the Cu-enriched mantle source.

In this xenolith suite, a group of deformed peridotites (refractory lherzolites to harzburgites) has been metasomatized by volatile-rich small melt-fractions while a group of granular peridotites (harzburgites to cpx-rich, fertile lherzolites) indicate extensive re-equilibration with high fractions of OIB-like melts at the bottom of the sub-continental lithosphere. The PGE data can be explained by a model combining a recent porous flow melt percolation event at variable melt-rock ratios superimposed on a protolith variably depleted by an old partial melting event. All PGE spectra have sub-chondritic Pt/Ir and Pt/Ru, decreasing with decreasing bulk-rock Al (sub 2) O (sub 3) contents, and thus inherited from the partial melting event; likewise, whether deformed or granular, all the harzburgites have PGE and S abundances characteristic of residues from high degree partial melting, i.e. almost no base metal sulfides (especially Mss) and Pd- and Au-depleted CI-normalized PGE patterns. The two textural groups of lherzolites display contrasting PGE abundances and sulfide modal compositions, both reflecting the differing recent magmatic histories of the two groups. In the deformed lherzolites, Pd and Au abundances increase relative to Pt and Ir in parallel with the amount of Al-poor metasomatic diopside and intergranular Cu-Ni-rich sulfides, also of indisputable metasomatic origin. For this textural group, transport and precipitation of S, Cu, Pd and Au from the volatile-rich small-melt fraction is likely. Despite their fertile bulk-rock compositions (up to 3.65 wt.% Al (sub 2) O (sub 3) contents) and evidence of metasomatic Fe-Ni-rich sulfides precipitated along with cpx, the granular lherzolites show surprisingly low total PGE contents (11.9-13.3 ppb) as well as sub-chondritic Pd/Ir ratios. Such a PGE budget can be explained by extensive re-equilibration between the OIB-like melts and Mss of residual origin, coupled with a mobility of sulfide melts in high-porosity zones of the lithospheric mantle. Our data indicate that porous flow melt percolation events may significantly alter the PGE budget of the sub-continental lithospheric mantle with respect to PUM estimates.

These data are coupled with corresponding (super 187) Re- (super 187) Os isotopic data reported by Walker et al. [Geochim. Cosmochim. Acta, 2002] in order to constrain the nature and timing of chemical fractionation relating to these elements in the early solar system. The suite of chondrites examined displays considerable variations in absolute abundances of the HSE, and in the ratios of certain HSE. Absolute abundances of the HSE vary by nearly a factor of 80 among the chondrite groups, although most vary within a factor of only 2. Variations in concentration largely reflect heterogeneities in the sample aliquants. Different aliquants of the same chondrite may contain variable proportions of metal and/or refractory inclusions that are HSE-rich, and sulfides that are HSE-poor. The relatively low concentrations of the HSE in CI1 chondrites likely reflect dilution by the presence of volatile components. Carbonaceous chondrites have Re/Os ratios that are, on average, approximately 8% lower than ratios for ordinary and enstatite chondrites. This is also reflected in (super 187) Os/ (super 188) Os ratios that are approximately 3% lower for carbonaceous chondrites than for ordinary and enstatite chondrites. Given the similarly refractory natures of Re and Os, this fractionation may have occurred within a narrow range of high temperatures, during condensation of these elements from the solar nebula. Superimposed on this major fractionation are more modest movements of Re or Os that occurred within the last 0-2 Ga, as indicated by minor open-system behavior of the Re-Os isotope systematics of some chondrites. The relative abundances of other HSE can also be used to discriminate among the major classes of chondrites. For example, in comparison to the enstatite chondrites, carbonaceous and ordinary chondrites have distinctly lower ratios of Pd to the more refractory HSE (Re, Os, Ir, Ru and Pt). Differences are particularly well resolved for the EH chondrites that have Pd/Ir ratios that average more than 40% higher than for carbonaceous and ordinary chondrite classes. This fractionation probably occurred at lower temperatures, and may be associated with fractionation processes that also affected the major refractory lithophile elements. Combined, (super 187) Os/ (super 188) Os ratios and HSE ratios reflect unique early solar system processing of HSE for each major chondrite class.

We evaluate the use of Hf and Ta, two highly incompatible elements, as sensitive indicators of partial melting or fractional crystallization processes. Comparison with rare earth element (REE) data from nonantarctic and Antarctic eucrites shows that Hf and Ta are unaffected by the terrestrial alteration that has modified the REE contents and patterns of some Antarctic eucrites. The major host phases for Hf and Ta--zircon, baddeleyite, ilmenite, and titanite--are much less susceptible to terrestrial alteration than the phosphate hosts of REEs. The host phases for Hf and Ta are minor or trace phases, so sample heterogeneity is a serious concern for obtaining representative compositions. The trace lithophile and siderophile element contents of noncumulate eucrites do not allow for a single, simple model for the petrogenesis of the howardite-eucrite-diogenite suite. Fractional crystallization models cannot reproduce the compositional relationship between eucrites of the main group-Nuevo Laredo trend and those of the Stannern trend. Equilibrium crystallization models cannot explain the trace element diversity observed among diogenites. Partial melting models cannot explain the W variations among eucrites, unless source regions had different metal contents. We suggest that slight variations in oxygen fugacity of eucrite source regions during partial melting can explain the W variations without requiring different metal contents. This hypothesis may fail to account for eucrite Co contents, however.

Hydrological interest has generally been in soil moisture of the root zone. Microwave Remote Sensing methods are now available that allow the interpretation of spatial distributions of soil moisture, however, their signals respond to moisture in the upper few centimetres of soil. These instruments are still being developed, but one of the questions surrounding their application is how to interpret the surface moisture in a hydrological context. In this study we compare measurements of soil moisture in 0-30 cm of soil with those in 0-6 cm to examine how representative this surface measure is with regard to the root zone.Detailed spatial measurements of soil moisture were conducted at three pasture sites in the 50 km (super 2) Mahurangi River catchment of northern New Zealand as part of a comprehensive hydrology project; MARVEX (MAhurangi River Variability EXperiment). In three field sites, on each of three occasions, field measurements were made using both 30 and 6 cm dielectric-based instruments. Spatial grids of several hundred moisture measurements were collected over 0-30 cm and compared with those collected simultaneously over 0-6 cm.Results indicate that temporal and spatial issues interfere with correlation of the two sets of series. Rapid wetting of 0-6 cm compared with 0-30 cm is seen following storm activity. Some evidence of the decoupling of moisture content response is also evident when sites are measured on days following a storm. Rapid, but not unrealistic, response to intense rainfall was also observed. Implications are that detailed and accurate knowledge of local soil conditions and a sound model of soil water redistribution are required before surface soil moisture measurements can be used to infer root zone behaviour. Such knowledge was not available in this study, from either published data or field observation. In this study, without suitable a priori knowledge, soil property information was found via calibration.

Past studies have shown that after most eucrites formed, they underwent metamorphism in temperatures up to > or =800 degrees C. Much later, many were brecciated and heated by large impacts into the parent body surface. The less common basaltic, unbrecciated eucrites also formed near the surface but, presumably, escaped later brecciation, while the cumulate eucrites formed at depths where metamorphism may have persisted for a considerable period. To further understand the complex HED parent body thermal history, we determined new (super 39) Ar- (super 40) Ar ages for 9 eucrites classified as basaltic but unbrecciated, 6 eucrites classified as cumulate, and several basaltic-brecciated eucrites. Precise Ar-Ar ages of 2 cumulate eucrites (Moama and EET 87520) and 4 unbrecciated eucrites give a tight cluster at 4.48+ or -0.02 Gyr (not including any uncertainties in the flux monitor age). Ar-Ar ages of 6 additional unbrecciated eucrites are consistent with this age within their relatively larger age uncertainties. By contrast, available literature data on Pb-Pb isochron ages of 4 cumulate eucrites and 1 unbrecciated eucrite vary over 4.4-4.515 Gyr, and (super 147) Sm- (super 143) Nd isochron ages of 4 cumulate and 3 unbrecciated eucrites vary over 4.41-4.55 Gyr. Similar Ar-Ar ages for cumulate and unbrecciated eucrites imply that cumulate eucrites do not have a younger formation age than basaltic eucrites, as was previously proposed. We suggest that these cumulate and unbrecciated eucrites resided at a depth where parent body temperatures were sufficiently high to cause the K-Ar and some other chronometers to remain as open diffusion systems. From the strong clustering of Ar-Ar ages at approximately 4.48 Gyr, we propose that these meteorites were excavated from depth in a single large impact event approximately 4.48 Gyr ago, which quickly cooled the samples and started the K-Ar chronometer. A large ( approximately 460 km) crater postulated to exist on Vesta may be the source of these eucrites and of many smaller asteroids thought to be spectrally or physically associated with Vesta. Some Pb-Pb and Sm-Nd ages of cumulate and unbrecciated eucrites are consistent with the Ar-Ar age of 4.48 Gyr, and the few older Pb-Pb and Sm-Nd ages may reflect an isotopic closure before the large cratering event. One cumulate eucrite gives an Ar-Ar age of 4.25 Gyr; 3 additional cumulate eucrites give Ar-Ar ages of 3.4-3.7 Gyr; and 2 unbrecciated eucrites give Ar-Ar ages of approximately 3.55 Gyr. We attribute these younger ages to a later impact heating. Furthermore, the Ar-Ar impact-reset ages of several brecciated eucrites and eucritic clasts in howardites fall within the range of 3.5-4.1 Gyr. Among these, Piplia Kalan, the first eucrite to show evidence for extinct (super 26) Al, was strongly impact heated approximately 3.5 Gyr ago. When these data are combined with eucrite Ar-Ar ages in the literature, they confirm that several large impact heating events occurred on Vesta between approximately 4.1-3.4 Gyr ago. The onset of major impact heating may have occurred at similar times for both Vesta and the moon, but impact heating appears to have persisted for a somewhat later time on Vesta.

One of them (#d4A) is a large crystal of albite with inclusions of fluorapatite, arfvedsonite, aenigmatite, and wilkinsonite. The two latter minerals were previously unknown in meteorites. Another clast (#d[3-5]D) has a melt crystallization texture of mainly feldspar (oligoclase) composition and contains relict grains of both high-Ca and low-Ca pyroxene and fluorapatite. The mineralogical characteristics of these clasts suggest a genetic relationship and an origin from the same parent body. The textural and mineralogical characteristics of the clasts indicate origin by extensive igneous differentiation. Such processes most likely took place in a rather large differentiated body. The material of clast #d(3-5)D is similar in some mineralogical respects to basaltic shergottites.

A rare CaCO (sub 3) polymorph, vaterite, is also observed. Physical and chemical conditions of the spring water and surrounding environment, as well as mineralogical and isotopic signatures, argue for biologically mediated redox reactions controlling sulfur.

These Ir and Os concentrations correlate with the Mg# [molar Mg/(Mg+Fe)], Cr and Ni, suggesting that olivine or chromite acts as a host for compatible siderophiles. Our analysis agrees with others who have suggested that the martian mantle has chondritic relative abundances of siderophiles. We also agree that, unlike the Sr and Nd isotopic systems, there is no evidence from Os isotopes for crustal assimilation. Comparisons of the siderophile element ratios of ALH 84001 to younger SNCs give no indication of a change in the martian siderophile element pattern over time.

Cells of the Gram-negative strain were motile and spirochaete-shaped with sizes of 0 times 2-0 times 22 times 8-18 mu m. Growth of the strain was observed between 10 and 44 degree C (optimum 37 degree C), in 2-12% (w/v) NaCl (optimum 3% NaCl) and between pH 8 and 10 times 5 (optimum pH 9 times 5). The novel strain was strictly alkaliphilic, required high concentrations of carbonates in the medium and was capable of utilizing D-glucose, fructose, maltose, sucrose, starch and D-mannitol. End products of glucose fermentation were H sub(2), acetate, ethanol and formate. Strain ASpG1 super(T) was resistant to kanamycin and rifampicin, but sensitive to gentamicin, tetracycline and chloramphenicol. The G + C content of its DNA was 58 times 5 mol%. DNA-DNA hybridization analysis of strain ASpG1 super(T) with its most closely related species, Spirochaeta alkalica Z-7491 super(T), revealed a hybridization value of only 48 times 7%. On the basis of its physiological and molecular properties, strain ASpG1 super(T) appears to represent a novel species of the genus Spirochaeta, for which the name Spirochaeta americana is proposed (type strain ASpG1 super(T) = ATCC BAA-392 super(T) = DSM 14872 super(T)).

Since then there has been a growing realization of the environmental significance of this source of gases, and of associated particulate material, and the effects range from the local through the regional to the global. Biomass burning also influences the biogeochemical cycling of carbon and nitrogen compounds from the soil to the atmosphere. Although most such burning occurs during human-initiated land clearance and changes in land use, a large component is due to the use of biomass fuels for domestic activities. That component has not previously been quantified. As they describe in the Journal of Atmospheric Chemistry, however, Ludwig and colleagues have now provided some estimates, and the figures concerned are substantial.

In support of the National Park Service (NPS) Vegetation Mapping Program (VMP), we have examined the feasibility of using a commercially available decision tree classifier with multitemporal satellite data from the Enhanced Thematic Mapper- Plus (ETM+) instrument to map 11 land cover types at the Delaware Water Gap National Recreation Area near Milford, PA. Ensemble techniques such as boosting and consensus filtering of the training data were used to improve both the quality of the input training data as well as the final products. Using land cover classes as specified by the National Vegetation Classification Standard at the Formation level, the final land cover map has an overall accuracy of 82% ( Kappa =0.80) when tested against a validation data set acquired on the ground (n=195). This same accuracy is 99.5% when considering only forest vs. nonforest classes. Usage of ETM+ scenes acquired at multiple dates improves the accuracy over the use of a single date, particularly for the different forest types. These results demonstrate the potential applicability and usability of such an approach to the entire National Park system, and to high spatial resolution land cover and forest mapping applications in general.

Characteristic electrochemical behaviors are observed for measuring bulk and surface-immobilized redox species. Sensitivity is dramatically improved by lowering the nanotube density. Oligonucleotide probes are selectively functionalized to the open ends of nanotubes. The hybridization of subattomole DNA targets can be detected by combining such electrodes with Ru(bpy) sub(3) super(2+) mediated guanine oxidation.

AN - 71505978; 14672085 AB - The use of the activated carbon produced from rice hulls to control NOx emissions for future deep space missions has been demonstrated. The optimal carbonization temperature range was found to be between 600 and 750 degrees C. A burnoff of 61.8% was found at 700 degrees C in pyrolysis and 750 degrees C in activation. The BET surface area of the activated carbon from rice hulls was determined to be 172 m2/g when prepared at 700 degrees C. The presence of oxygen in flue gas is essential for effective adsorption of NO by activated carbon. On the contrary, water vapor inhibits the adsorption efficiency of NO. Consequently, water vapor in flue gas should be removed by drying agents before adsorption to ensure high NO adsorption efficiency. All of the NO in the flue gas was removed for more than 1.5 h when 10% oxygen was present and the ratio of the carbon weight to the flue gas flow rate (W/F) was 15.4 g min/L. Reduction of the adsorbed NO to form N2 could be effectively accomplished under anaerobic conditions at 550 degrees C. The adsorption capacity of NO on the activated carbon was found to be 5.02 mg of NO/g of carbon. The loss of carbon mass was determined to be about 0.16% of the activated carbon per cycle of regeneration if the regeneration occurred when the NO in the flue gas after the carbon bed reached 4.8 ppm, the space maximum allowable concentration. The reduction of the adsorbed NO also regenerated the activated carbon, and the regenerated activated carbon exhibited an improved NO adsorption efficiency.

AN - 85364889; pmid-12795480 AB - Repetition priming is easily elicited in many traditional paradigms, and the possibility that perceptual priming may be other than an automatic consequence of perception has received little consideration. This issue is explored in two experiments. In Experiment 1, participants named the target from a four-item category search study task more quickly than the nontarget study items at a later naming test. Experiment 2 extended this finding to conditions in which stimuli were individually presented at study. In three different study tasks, stimuli relevant to study-task completion elicited priming on a later test, but stimuli presented outside the context of a task did not. In both experiments, recognition was above chance for nonrelevant stimuli, suggesting that participants explicitly remembered stimuli that did not elicit priming. Results suggest that priming is sensitive to study-task demands and may reflect a more adaptive and flexible mechanism for modification of perceptual processing than previously appreciated.

AN - 73218792; 12703699 AB - Attenuation in a gas results from a combination of classical attenuation, attenuation from diffusion, and attenuation due to molecular relaxation. In previous papers [J. Acoust. Soc. Am. 109, 1955 (2001); 110, 2974 (2001)] a model is described that predicts the attenuation from vibrational relaxation in gas mixtures. In order to validate this model, the attenuation was measured using a pulse technique with four transducer pairs, each with a different resonant frequency. The attenuation calculated using the model was compared to the measured values for a variety of gases including: air, oxygen, methane, hydrogen, and mixtures of oxygen/nitrogen, methane/nitrogen, carbon dioxide/nitrogen, and hydrogen/nitrogen. After the measured data is corrected for diffraction, the model matches the trends in the measured attenuation spectrum for this extensive set of gas mixtures. c2003 Acoustical Society of America.

AN - 73013649; 12575722 AB - Heavy water containing deuterium displays toxic property. It is stated that any quantity of a heavy isotope of hydrogen--deuterium--is undesirable to animals and plants. It was earlier shown by us that physical-chemical life support systems on board the "MIR" station fractionate (change) isotopes of hydrogen, oxygen and carbon. Therefore, the problem of regenerative systems in habitable space objects should include removal, from water, of a heavy stable isotope of hydrogen--deuterium. In this article we consider one method of obtaining deuterium-free water--decomposition of distillate water in an electrolyser to hydrogen and oxygen with subsequent synthesis in a catalytic or high-temperature reactor. The influence of deuterium-free water on the growth and development of Arabidopsis thaliana and Japanese quail is investigated. It is shown that with the help of the electrolysis method it is possible to fabricate water containing 80% less deuterium in comparison with SMOW. Experimentally, it is proved on a culture of Arabidopsis thaliana and Japanese quail that water with reduced contents of deuterium (80%) displays positive biological activity. c2002 Elsevier Science Ltd.

Their extrasolar origins are demonstrated by their extremely anomalous oxygen isotopic compositions. Three (super 17) O-rich grains appear to originate from red giant or asymptotic giant branch stars. One (super 16) O-rich grain may be from a metal-poor star. Two (super 16) O-poor grains have unknown stellar sources. One of the grains is forsterite, and two are amorphous silicate "GEMS" (glass with embedded metal and sulfides), which is consistent with astronomical identifications of crystalline and amorphous silicates in the outflows of evolved stars. These observations suggest cometary origins of these IDPs and underscore the perplexing absence of silicates among circumstellar dust grains from meteorites.

L-Enantiomeric excesses of the amino acid were found to range from 0 to 15.2%, varying significantly both between meteorite stones and at short distances within a single stone. The upper limit of this range is the largest enantiomeric excess measured to date for a biologically rare meteoritic amino acid and raises doubts that circularly polarized light irradiation could have been the sole cause of amino acids chiral asymmetry in meteorites. Individual D- and L-isovaline delta (super 13) C values ware found to be about +18 per mil, with no significant differences between the two enantiomers to suggest terrestrial contamination. The amino acid relative abundance also varied between samples, with isovaline/alanine ratios of 0.5 to 6.5. X-ray diffraction analyses of contiguous meteorite fragments suggest a possible correlation between isovaline and hydrous silicates abundances.

Uplifts and flanking basins also formed within the Laurentian Midcontinent. On the Gondwanan continent, well inboard from the marginal fold belts, a counterpart structural array developed during the same period. Intraplate deformation began when full collisional plate coupling had been achieved along the continental margin; the intervening ocean had been closed and subduction had ceased--that is, the distinction between upper versus lower plates became moot. Ancestral Rockies deformation was not accompanied by volcanism. Basement shear zones that formed during Mesoproterozoic rifting of Laurentia were reactivated and exerted significant control on the locations, orientations, and modes of displacement on late Paleozoic faults. Ancestral Rocky Mountain uplifts extend as far south as Chihuahua and west Texas (28 degrees to 33 degrees N, 102 degrees to 109 degrees W) and include the Florida-Moyotes, Placer de Guadalupe-Carrizalillo, Ojinaga-Tascotal and Hueco Mountain blocks, as well as the Diablo and Central Basin Platforms. All are cored with Laurentian Proterozoic crystalline basement rocks and host correlative Paleozoic stratigraphic successions. Pre-late Paleozoic deformational, thermal, and metamorphic histories are similar as well. Southern Ancestral Rocky Mountain structures terminate along a line that trends approximately N40 degrees E (present coordinates), a common orientation for Mesoproterozoic extensional structures throughout southern to central North America. Continuing Tien Shan intraplate deformation (Central Asia) has created an analogous array of uplifts and basins in response to the collision of India with Eurasia, beginning in late Miocene time when full coupling of the colliding plates had occurred. As in the Laurentia-Gondwana case, structures of similar magnitude and spacing to those in Eurasia have developed in the Indian plate. Within the present orogen two ancient suture zones have been reactivated--the early Paleozoic Terskey zone and the late Paleozoic Turkestan suture between the Siberian and East Gondwanan cratons. Inverted Proterozoic to early Paleozoic rift structures and passive-margin deposits are exposed north of the Terskey zone. In the Alay and Tarim complexes, Vendian to mid-Carboniferous passive-margin strata and the subjacent Proterozoic crystalline basement have been uplifted. Data on Tien Shan uplifts, basins, structural arrays, and deformation rates guide paleotectonic interpretations of ancient intraplate mountain belts. Similarly, exhumed deep crustal shear zones in the Ancestral Rockies offer insight into partitioning and reorientation of strain during contemporary intraplate deformation.

A combination of key parameters including whole-rock oxygen isotopic composition, Fe/Mn ratios in mafic silicates, noble gas concentrations, a KREEP-like rare earth element pattern, and the presence of regolith agglutinate fragments indicate a lunar origin for NWA 773. Partial maskelynitization of feldspar and occasional twinning of pyroxene are attributed to shock deformation. Terrestrial weathering has caused fracturing and precipitation of Carich carbonates and sulfates in the fractures, but lunar minerals appear fresh and unoxidized. The meteorite is composed of two distinct lithologies: a two-pyroxene olivine gabbro with cumulate texture, and a polymict, fragmental regolith breccia. The olivine gabbro is dominated by cumulate olivine with pigeonite, augite, and interstitial plagioclase feldspar. The breccia consists of several types of clasts but is dominated by clasts from the gabbro and more FeO-rich derivatives. Variations in clast mineral assemblage and pyroxene Mg/(Mg + Fe) and Ti(Ti + Cr) record an igneous Fe-enrichment trend that culminated in crystallization of fayalite + silica + hedenbergite-bearing symplectites. The Fe-enrichment trend and cumulate textures observed in NWA 773 are similar to features of terrestrial ponded lava flows and shallow-level mafic intrusives, indicating that NWA 773 may be from a layered mafic intrusion or a thick, differentiated lava flow. NWA 773 and several other mafic lunar meteorites have LREE-enriched patterns distinct from Apollo and Luna mare basalts, which tend to be LREE-depleted. This is somewhat surprising in light of remote sensing data that indicates that the Apollo and Luna missions sampled a portion of the moon that was enriched in incompatible heat-producing elements.

The clast (designated 67215c) has an unusually well preserved igneous texture. Mineral compositions are consistent with classification of 67215c as a member of the ferroan anorthositic suite of lunar highlands rocks, but the texture and mineralogy show that it cooled more rapidly and at shallower depths than did more typical ferroan anorthosites (FANs). Incompatible trace element concentrations are enriched in 67215c relative to typical FANs, but diagnostic signatures such as Ti/Sm, Sc/Sm, plagiophile element ratios, and the lack of Zr/Hf and Nb/Ta fractionation show that this cannot be due to the addition of KREEP. Alternatively, 67215c may contain a greater fraction of trapped liquid than is commonly present in lunar FANs. (super 147) Sm- (super 143) Nd isotopic compositions of mineral separates from 67215c define an isochron age of 4.40+ or -0.11 Gyr with a near-chondritic initial epsilon (super 143) Nd of +0.85+ or -0.53. The (super 40) Ar- (super 39) Ar composition of plagioclase from this clast records a post-crystallization thermal event at 3.93+ or -0.08 Gyr, with the greatest contribution to the uncertainty in this age deriving from a poorly constrained correction for lunar atmosphere (super 40) Ar. Rb-Sr isotopic compositions are disturbed, probably by the same event recorded by the Ar isotopic compositions. Trace element compositions of FANs are consistent with crystallization from a moderately evolved magma ocean and do not support a highly depleted source composition such as that implied by the positive initial epsilon (super 143) Nd of the ferroan noritic anorthosite 62236. Alternatively, the Nd isotopic systematics of lunar FANs may have been subject to variable degrees of modification by impact metamorphism, with the plagioclase fraction being more strongly affected than the mafic phases. (super 147) Sm- (super 143) Nd isotopic compositions of mafic fractions from the 4 ferroan noritic anorthosites for which isotopic data exist (60025, 62236, 67016c, 67215c) define an age of 4.46+ or -0.04 Gyr, which may provide a robust estimate for the crystallization age of lunar ferroan anorthosites.

With support from NASA, USGS, and several local agencies, the Puget Sound Lidar Consortium is working with a commercial contractor to acquire lidar topographic data and create high-resolution digital elevation models (DEMs) of the forested terrain of western Washington. To date the Consortium has acquired 10,000 sq km of 6-ft DEM with vertical accuracy of circa 30 cm RMSE. For details on this effort, see http://pugetsoundlidar.org. Several probable Holocene fault scarps have been identified from the new lidar DEMs. Subsequent trenching studies indicate several large (M 6.5-7.5) crustal earthquakes in the last few thousand years. Locally we have used the DEMs to measure marine shoreline terrace elevations and quantify uplift and tilting produced by these earthquakes. Geomorphic mapping from the DEMS is refining our understanding of surficial geology (e.g. the distribution of bedrock, alluvium, artificial fill) that controls earthquake site response and will lead to improved earthquake hazard maps. This mapping may delimit the shores of short-lived late-glacial lakes with sufficient detail that we can describe aggregate Holocene vertical deformation throughout the Puget Lowland at the 1-m level. From the lidar DEMs we are developing a regional inventory of large, deep-seated landslides that is more complete and more consistent than the present inventory based on aerial photography and field studies. Several large, spectacular, previously unknown landslides have been recognized. Areas with significant potential for small landslides can be delineated. Lidar DEMs are serving to define areas prone to flood and tsunami inundation and to study mitigation measures. We are now acquiring lidar topography on the west flank of Mount Rainier and we expect these data to provide important information on lahar processes, deposits, and hazards. Finally, we have learned that high-resolution DEMs provide an extremely effective map base on which to communicate the results of hazards studies.

Distinct arrays of interconnected polygons characterize many surfaces, reflecting a subsurface network of interconnected, subvertical wedges of sand that grow incrementally as sand progressively fills soil fractures.

Two insect outbreaks were studied: Ket-Chulym, similar to 1.5 million hectares of forest damaged between 1954 and 1957; and Priangar'e, similar to 0.5-0.7 million hectares of forest damaged between 1994 and 1996. Landsat scenes from 1980 to 2000 were analyzed. The optimal Landsat channels combination for detecting damage classes were bands 2 (0.525-0.605 mu m), 4 (0.750-0.900 mu m), 5 (1.55-1.75 mu m), and 6 (10.40-12.50 mu m). The damage to the forests caused an increase in radiometric temperature (20.20 plus or minus 0.04 degree C for damaged forests versus 19.47 plus or minus 0.02 degree C for healthy forests). The following pattern of forest succession was observed in the outbreak areas: dead stands with dense grass and shrub communities, burn scars, grass and shrub formations, open woodlands, closed young and middle-age birch stands, mature birch stands, and mixed conifer-deciduous stands. Forest regeneration goes through long-term species-change successions, and the rate depends on the size of the outbreak area. On-ground mapping after the outbreak and later Landsat analysis showed that even 45 years after the Ket-Chulym outbreak the area of forests did not increase. In the Priangar'e area approximately 45% of damaged forests have recovered.Original Abstract: Des donnees Landsat thematic mapper (TM) et enhanced thematic mapper (ETM+) ont ete utilisees pour examiner l'effet des infestations a grande echelle d'insectes dans les forets du sud de la Siberie. Deux zones d'infestations ont ete etudiees : une zone de foret de similar to 1,5 million d'ha endommagee entre 1954 et 1957 (Ket-Chulym), et une infestation couvrant similar to 0,5-0,7 million d'ha enregistree en 1994 et 1996 (Priangar'e). Des scenes Landsat de 1980 a 2000 ont ete analysees. Les combinaisons optimales des canaux Landsat permettant de detecter les classes de dommage etaient : la bande 2 (0,525-0,605 mu m), la bande 4 (0,750-0,900 mu m), la bande 5 (1,55-1,75 mu m) et la bande 6 (10,40-12,50 mu m). Les dommages subis par les forets ont aussi entraine un accroissement apparent de la temperature radiometrique. Dans les zones d'infestations, le patron suivant de succession forestiere a ete observe : des peuplements morts avec des communautes d'herbes denses et d'arbustes, des cicatrices d'incendies, des formations composees d'herbes et d'arbustes, des zones de forets ouvertes, des peuplements fermes de bouleaux jeunes et d'age moyen, des peuplements de bouleaux matures, et des peuplements mixtes de coniferes-feuillus. La regeneration forestiere traverse une periode de successions de changements a long terme des especes, le taux variant en fonction de la superficie de la zone d'infestation. A Ket-Chulym, la cartographie realisee au sol peu de temps apres l'infestation et l'analyse realisee ulterieurement a l'aide des donnees Landsat ont montre que, meme 45 ans apres l'infestation, les surfaces de forets endommagees ne se sont toujours pas encore retablies significativement. Dans la region de Priangar'e, approximativement 45% des forets endommagees sont en voie de retablissement.

These mats may be direct descendents of the most ancient biological communities in which even oxygenic photosynthesis might have developed. Photosynthetic mats are excellent natural laboratories to help us to learn how microbial populations associate to control dynamic biogeochemical gradients.

Each monitoring station provides near-real-time measurements of the surface skin temperature and bulk temperature on a near-continuous basis. Day and night data, acquired over Lake Tahoe from March to August 2000 with the second Along-Track Scanning Radiometer (ATSR-2), have been analyzed, and sets of coefficients for recovering the skin temperature and bulk temperature of the lake have been derived. The field measurements indicate that there is a noticeable difference between the bulk and skin temperatures (skin effect), which varies over the diurnal cycle. At the time of the ATSR-2 daytime overpass, the skin temperatures are on average 0.11 degree C cooler than the daytime bulk temperatures. At the time of the nighttime ATSR-2 overpass, the skin temperatures are on average 0.46 degree C cooler than the nighttime bulk temperatures. The smaller skin effect during the day is attributed to strong solar heating and low wind speeds at the site in the morning.The standard errors for recovering the daytime bulk and nighttime bulk temperatures, by regressing the in situ measurements against the average ATSR-2 nadir 11- and 12- mu m channel brightness temperatures, are 0.40 degree and 0.18 degree C, respectively. By comparison the standard errors for recovering the daytime skin and nighttime skin temperatures by the same approach are 0.33 degree and 0.28 degree C, respectively. The lower standard error obtained for recovery of the skin and bulk temperatures at night is attributed to the lake surface being more homogeneous with the absence of solar heating.A comparison between the measured skin temperatures, skin temperature recovered by an ATSR-2 two-channel sea surface temperature algorithm, and the in situ regression indicates that the ATSR-2 algorithm has a similar scatter to the in situ linear regression but is offset with respect to the measured skin temperatures.

Highly variable surface Chl a concentrations (0.1 to 17 mg m super(-3)) and colored dissolved organic matter (CDOM) absorption (0.07 to 1.1 m super(-1) at 412 nm) were observed in the study region that generally decreased with increasing salinity waters, being highest nearshore and decreasing at offshore stations. The optical properties of absorption, scattering, and diffuse attenuation coefficients reflected these distributions with phytoplankton particles and CDOM contributing to most of the spatial, vertical, and seasonal variability. The diffuse attenuation coefficient K sub(d)( lambda ) and spectral remote sensing reflectance R sub(rs)( lambda ) were linear functions of absorption and backscattering coefficients a( lambda ) and b sub(b)( lambda ) through the downward average cosine mu sub(d) and the ratio of variables f/Q at the SeaWiFS wavebands for waters with widely varying bio-optical conditions. Although various R sub(rs)( lambda ) ratio combinations showed high correlation with surface Chl a concentrations and CDOM absorption at 412 nm, power law equations derived using the R sub(rs)(490)/R sub(rs)(555) and R sub(rs)(510)/R sub(rs)(555) ratios provided the best retrievals of Chl a concentrations and CDOM absorption from SeaWiFS reflectance data.

For each boreal summer during 1997-2001, two 16-member ensembles of 3-month simulations were generated. The first, 'AMIP style' (Atmospheric Model Intercomparison Project) ensemble establishes the degree to which a perfect prediction of SSTs would contribute to the seasonal prediction of precipitation and temperature over continents. The second ensemble is identical to the first, except that the land surface is also initialized with 'realistic' soil moisture contents through the continuous prior application (within GCM simulations leading up to the start of the forecast period) of a daily observational precipitation dataset and the associated avoidance of model drift through the scaling of all surface prognostic variables. A comparison of the two ensembles shows that land initialization has a statistically significant impact on summertime precipitation over only a handful of continental regions. These regions agree, to first order, with those that satisfy three conditions: 1) a tendency toward large initial soil moisture anomalies, 2) a strong sensitivity of evaporation to soil moisture, and 3) a strong sensitivity of precipitation to evaporation. The impact on temperature prediction is more spatially extensive. The degree to which the initialization increases the skill of the forecasts is mixed, reflecting a critical need for the continued development of model parameterizations and data analysis strategies.

We sequenced the gene for the gamma subunit and studied the temperature-dependent changes in alpha, beta and gamma expression, their association into rosettasomes and their phylogenetic relationships. Alpha and beta gene expression was increased by heat shock (30 min, 86 degree C) and decreased by cold shock (30 min, 60 degree C). Gamma expression was undetectable at heat shock temperatures and low at normal temperatures (75-79 degree C), but induced by cold shock. Polyacrylamide gel electrophoresis indicated that in vitro alpha and beta subunits form homo-oligomeric rosettasomes, and mixtures of alpha, beta and gamma form hetero-oligomeric rosettasomes. Transmission electron microscopy revealed that beta homo-oligomeric rosettasomes and all hetero-oligomeric rosettasomes associate into filaments. In vivo rosettasomes were hetero-oligomeric with an average subunit ratio of 1 alpha :1 beta :0.1 gamma in cultures grown at 75 degree C, a ratio of 1 alpha :3 beta :1 gamma in cultures grown at 60 degree C and a ratio of 2 alpha :3 beta :0 gamma after 86 degree C heat shock. Using differential scanning calorimetry, we determined denaturation temperatures (T sub(m)) for alpha, beta and gamma subunits of 95.7 degree C, 96.7 degree C and 80.5 degree C, respectively, and observed that rosettasomes containing gamma were relatively less stable than those with alpha and/or beta only. We propose that, in vivo, the rosettasome structure is determined by the relative abundance of subunits and not by a fixed geometry. Furthermore, phylogenetic analyses indicate that archaeal chaperonin subunits underwent multiple duplication events within species (paralogy). The independent evolution of these paralogues raises the possibility that chaperonins have functionally diversified between species.

The Collatz et al. parameterization of leaf photosynthesis-stomatal conductance has been widely applied in land surface parameterization schemes for simulating the land surface CO sub(2) fluxes. The study in this paper developed an analytical solution approach for the Collatz et al.'s parameterization for stable solution and computational efficiency. This analytical approach is then applied to the simplified biosphere model (SSiB), enhancing its capability of simulating land surface CO sub(2) fluxes. The enhanced SSiB model is tested with field observation data sets from two Amazonian field experiments (ABRACOS missions and Manaus Eddy Covariance Study). Simulations of the land surface fluxes of latent heat, sensible heat and soil heat by the enhanced SSiB agree very well with observations with correlation coefficients being larger than 0.80. However, the correlation coefficient for the daily means of CO sub(2) fluxes is only 0.42 for the Manaus data set. A day-time 'square wave' in the simulated CO sub(2) flux diurnal curves is found. The discrepancies between simulation and observation were found to be the results of incorrect parameter setup or improper leaf to canopy scaling strategy. A modification to the scaling strategy improves significantly the accuracy of the photosynthesis-stomatal conductance model.

We used 4 years of Tropical Rainfall Measuring Mission (TRMM) Visible and Infrared Scanner (VIRS) satellite data and a biogeochemical model to assess spatial and temporal variability of carbon emissions from tropical fires. The TRMM satellite data extended between 38 degree N and 38 degree S and covered the period from 1998 to 2001. A relationship between TRMM fire counts and burned area was derived using estimates of burned area from other satellite fire products in Africa and Australia and reported burned areas from the United States. We modified the Carnegie-Ames-Stanford-Approach (CASA) biogeochemical model to account for both direct combustion losses and the decomposition from fire-induced mortality, using both TRMM and Sea-viewing Wide Field of view Sensor (SeaWiFS) satellite data as model drivers. Over the 1998-2001 period, we estimated that the sum of carbon emissions from tropical fires and fuel wood use was 2.6 Pg C yr super(-1). An additional flux of 1.2 Pg C yr super(-1) was released indirectly, as a result of decomposition of vegetation killed by fire but not combusted. The sum of direct and indirect carbon losses from fires represented 9% of tropical and subtropical net primary production (NPP). We found that including fire processes in the tropics substantially alters the seasonal cycle of net biome production by shifting carbon losses to months with low soil moisture and low rates of soil microbial respiration. Consequently, accounting for fires increases growing season net flux by similar to 12% between 38 degree N and 38 degree S, with the greatest effect occurring in highly productive savanna regions.

The passage of African wave disturbances (AWDs) at each station was detected as statistically significant wavelet amplitudes within two spectral bands. The detected AWD activity, or lack of it, was compared with the precipitation record at each station. Results demonstrate that AWDs account for only a proportion of the seasonal rainfall, implying that other precipitation triggers are also important. In addition, the analysis finds that many AWD traversals fail to initiate heavy rainfall at the selected stations. At Niamey, the average precipitation amount per wave had a positive trend between 1953 and 1978. With few exceptions, seasonal precipitation totals were not correlated with the number of days on which AWDs were detected. Although the seasonal average precipitation amount per AWD day exhibited a positive trend at Niamey between 1953 and 1978, there was no corresponding interannual trend in total seasonal precipitation.

AN - 73611450; 12934605 AB - Described is the Liulin-5 active dosimetric telescope designed for measurement of the space radiation dose depth-distribution in a human phantom on the Russian Segment of the International Space Station (ISS). The Liulin-5 experiment is a part of the international project MATROSHKA-R on ISS. The MATROSHKA-R project is aimed to study the depth-dose distribution at the sites of critical organs of the human body, using models of human body-anthropomorphic and spherical tissue-equivalent phantoms. The aim of Liulin-5 experiment is a long term (4-5 years) investigation of the radiation environment dynamics inside the spherical tissue-equivalent phantom, mounted in different compartments. Energy deposition spectra, linear energy transfer spectra, and flux and dose rates for charged particles will be measured simultaneously with near real time resolution at different depths of the phantom by means of three silicon detectors. Data obtained together with data from other active and passive dosimeters will be used to estimate the radiation risk to the crewmembers, which verify the models of radiation environment in low Earth orbit. Presented are the test results of the prototype unit. Liulin-5 will be flown on the ISS in the year 2003. c2003 COSPAR. Published by Elsevier Science Ltd. All rights reserved.

AN - 73544592; 12959140 AB - A high-power, narrow-linewidth Yb fiber laser with a fiber Bragg grating (FBG) pumped difference frequency generation (DFG) in a periodically poled lithium niobate (PPLN) crystal was investigated in detail. A mid-IR power of approximately 2.3 microW at 3.3 micrometers with a slope efficiency of 0.85 mW/W2 was achieved. A Doppler-broadened absorption spectrum of CH4 at 3038.497 cm-1 (3.2911 micrometers) was obtained with a 0.1-m long-gas cell at a pressure of 133 Pa. The linewidth of the DFG source was evaluated to be less than 96 MHz from the observed spectral linewidth. Real-time monitoring of CH4 (approximately 1.78 ppm) in ambient air in a multipass cell which has an optical path length of 10 m was also demonstrated.

The Moderate Resolution Imaging Spectroradiometer (MODIS) launched on the National Aeronautics and Space Administration Terra and Aqua spacecrafts is equipped with narrow channels located within a wider wavelength range between 0.4-2.5 mu m for a variety of remote sensing applications. The wide spectral range can provide improved capabilities for remote sensing of the more complex and turbid coastal waters (Case 2 water) and for improved atmospheric corrections for ocean scenes. In this paper, we describe an empirical algorithm that uses this wide spectral range to identify areas with suspended sediments in turbid waters and shallow waters with bottom reflections. The algorithm takes advantage of the strong water absorption at wavelengths longer than 1 mu m that does not allow illumination of sediments in the water or a shallow ocean floor. MODIS data acquired over the east coast of China, west coast of Africa, Arabian Sea, Mississippi Delta, and west coast of Florida are used in this study.

It also contains amino acids that may have served as the necessary components for the origin of life. Magnetic analyses of Murchison identify an ultrasoft magnetic component due to superparamagnetism as a significant part of the magnetic remanence. The rest of the remanence may be due to electric discharge in the form of lightning bolts that may have formed the amino acids. The level of magnetic remanence does not support this possibility and points to a minimum ambient field of the remanence acquisition. We support our observation by showing that normalized mineral magnetic acquisition properties establish a calibration curve suitable for rough paleofield determination. When using this approach, 1-2% of the natural remanence left in terrestrial rocks with TRM and/or CRM determines the geomagnetic field intensity irrespective of grain size or type of magnetic mineral (with the exception of hematite). The same method is applied to the Murchison meteorite where the measured meteorite remanence determines the paleofield minimum intensity of 200-2000 nT during and/or after the formation of the parent body.

The most probable age is K/T boundary, but it lacks definitive ages from impact materials. Regional apatite fission track data show a reheating event probably beginning in the late Cretaceous. ODP sites show the K/T boundary sequence is centimeters to meters thick close to the Small Point (SP) structure while well away from the Chicxulub crater. The most distinctive features of the SP crater are its topographic and magnetic expressions. The submarine topography of the Gulf of Maine suggest an inner most ring partially disrupted by later glacial scraping. An outer ring, disrupted by possible resurge gullies, is also visible on the deeper parts of the shelf. This 140 km diameter outer ring is the basis for our minimum estimate of the impact structure size. This outer ring appears to be disrupted by at least two resurge gullies on its eastern edge. The orientation of the resurge gullies is perpendicular to the trend of glacial movement and thus is not glacially derived. Just inside the eastern edge of the outer ring, there is an extremely large magnetic anomaly. This anomaly is the only feature on the east coast of North America comparable in magnitude to the ocean-continental boundary magnetics. The line of magnet anomalies along the coasts of Maine and Massachusetts continue off shore and may define the elliptical crater rim, sized 325 X 400 km. We are presently assembling and searching seismic data for confirmation of an impact melt body in proximity to the magnetic high, and for impact ejecta outside the inner ring. Ballistic trajectory models show that the Small Point crater lies along a sub orbital trajectory extending from Chicxulub to two European K/T boundary craters: Silverpit and Boltysh. Orbit mechanics shows that Chicxulub and SP may have been a double impact event with only a few minutes separating the two, and tightly constrains their trajectories. The SP impact atmospheric shock wave could have effected the ejecta distribution from Chicxulub. The tsunami produced by SP may have shaped much of the topography of the Maritime provinces. The SP impact effected the regional fault systems may influence the contemporary distribution of seismicity.

The normal formulations used to adjust production rates for spatial differences due to geomagnetic latitude and atmospheric depth use a standard atmosphere model. J. Stone (2000, JGR, 102, 23752-23759) showed that for exposure ages requiring more precise scaling adjustments it is necessary to account for quasi-stationary atmospheric pressure anomalies as revealed from 30 years of averaged barometry. In places such as Antarctica, scaled production rates calculated using the standard atmosphere model deviate more than 5% from Stone's atmospheric model. However, to determine production rates for samples with exposure durations that include one or more glaciations, scaling should include the effects of both a redistribution of atmospheric pressure and the compression of atmosphere due to cooling. Because the magnitude of these deviations varies spatially and temporally, we calculate the production rates as a function of atmospheric pressure derived from a CCM3 simulation that reproduces Stone's present day measured global pressure records within 1%. To calculate the influence of production rates due to climate change at 20 ka and determine the percentage deviation from the modern-day scaled production rates, we use a paleoclimate simulation that incorporates the University of Maine Ice Sheet Model global ice cover. For sea level sites away from paleo-glaciers, the effects will be minimum. Without considering atmosphere compression, production rates for surfaces with 20 kyr of exposure at high altitude (3 km) overestimate the production rate by >3%. For longer durations, the effect will be greater. Places near large ice volume changes show higher sensitivity, particularly where high katabatic winds develop. This climate effect on atmospheric shielding may explain some of the small remaining disparities in production rate calibrations from sites at different altitudes and proximity to paleo-ice sheet margins.

The predominant broad-scale pattern seen at all sites is a major shift in moisture regimes from wet to dry, or vice versa (depending on location), that occurred after a period of relative stability. These large-scale shifts at the different sites exhibit spatial coherence at regional scales. The three Canadian sites record this abrupt shift between anno Domini 500 and 800, and subsequently conditions become increasingly variable. All three U.S. sites underwent a pronounced change, but the timing of this change is between anno Domini 1000 and 1300, thus later than in all of the Canadian sites. The mechanisms behind these patterns are poorly understood, but they are likely related to changes in the shape and location of the jet stream and associated storm tracks. If the patterns seen at these sites are representative of the region, this observed pattern can have huge implications for future water availability in this region.

McKay et al. originally suggested that some of the magnetite crystals associated with carbonate globules in Martian Meteorite ALH84001 are biogenic in origin, because they are single magnetic domain, free of crystalline defects, chemically pure, and coexist with other metastable phases in apparent disequilibrium. Thomas-Keprta et al. reported that a subpopulation of magnetite crystals (approx. 25%) associated with carbonate globules in ALH84001 and magnetite crystals produced by magnetotactic bacterial strain MV-1 have similar morphologies with crystal elongation along the [111] crystallographic axis that they describe as "truncated hexa-octahedral" ([111-THO]) magnetite. Along with several other properties, the [111]-THO morphology has been proposed to constitute a biomarker (i.e., formed only in biogenic processes), so that the presence of [111]-THO magnetite in ALH84001 may be evidence for past life on Mars.

Unfortunately, many "biomarkers" are not conclusive markers of biology. For example, sugars, amino acids, polycyclic aromatic hydrocarbons (PAH) and certain bacteria-like morphologies can all be produced non-biologically. Inferences of life following the detection of several inconclusive biomarkers in one sample will always be questioned. Although DNA, RNA and proteins are excellent markers of biology, and preserved on Earth for several millions of years, their survival over longer periods of time is low. Ideally, we should target biomarkers which are both stable over time and formed exclusively from biological processes, i.e. a "category 1" biomarker under the new classification system of Mckay.

These derived parameters are compared with parameters estimated from near concurrent measurements made by the SSMI and SSM/T-2 over snow-covered areas. It is shown that the MIR-estimated [xi]( nu ) values at nu =89 and 150 GHz agree well with those estimated from the SSM/T-2 at nu =91 and 150 GHz, respectively. Low MIR- estimated [xi]( nu ) values are generally associated with high NDSI and R87 over the snow-covered areas. Over forested areas, more fluctuations in the values of MIR-estimated [xi]( nu ), NDSI and R87, as well as a reduction in polarization index (PI) at 37 and 85 GHz are observed. Both observations and results from radiative transfer calculations show a change in the difference between brightness temperatures (T sub(b)) at 19 and 37 GHz, as well as PI at 37 and 85 GHz, when measured at satellite altitudes and at the surface. The amplitude of the T sub(b) difference and PI is reduced by about 10-15% from surface to high altitudes when integrated water vapor is [less-than or equal to]1.5 g/cm. This effect is readily correctable and requires consideration when validating satellite retrieval algorithms based on surface and low-elevation aircraft measurements.

Evidence for the feedback is sought in a 50-year observational precipitation dataset covering the United States. The precipitation variance and autocorrelation fields are characterized by features that agree (in structure, though not in magnitude) with those produced by an atmospheric general circulation model (AGCM). Because the model- generated features are known to result from land-atmosphere feedback alone, the observed features are suggestive of the existence of feedback in nature.

Statistical tests indicate that the regression model can be used to represent the relation between forest biomass and NDVI across spatial, temporal and ecological scales for relatively long time scales. For the 1.42 billion ha of boreal and temperate forests in the Northern Hemisphere, the woody biomass carbon pools and sinks are estimated at a relatively high spatial resolution (8x8 km). We estimate the carbon pool to be 61 plus or minus 20 gigatons (10) carbon (Gt C) during the late 1990s and the biomass sink to be 0.68 plus or minus 0.34 Gt C/year between the 1982 and 1999. The geographic detail of carbon sinks provided here can contribute to a potential monitoring program for greenhouse gas emission reduction commitments under the Kyoto Protocol.

For comparison, samples were taken from both clean-rooms, where the air was filtered to remove particles >0.5 mu m, and ordinary rooms with unfiltered air. The intracellular ATP was determined after enzymatically degrading the sample's free ATP. Also for comparison, cultivable microbial populations were counted on nutrient-rich trypticase soy agar (TSA) plates. Both the cultivable and ATP-based determinations indicate that the microbial burden was lower in clean-room facilities than in ordinary rooms. However, there was no direct correlation between the two sets of measurements because the two assays measured very different populations. A large fraction of the samples yielded no colony formers on TSA, but were positive for intracellular ATP. Subsequently, genomic DNA was isolated directly from selected samples and 16S rDNA fragments were cloned and sequenced, identifying nearest neighbors, many of which are known to be noncultivable in the media employed. It was concluded that viable microbial contamination can be reliably monitored by measurement of intracellular ATP, and that this method may be considered superior to cultivable colony counts due to its speed and its ability to report the presence of viable but noncultivable organisms. When the detection of nonviable microbes is of interest, the ATP assay can be supplemented with DNA analysis.

AN - 72953830; 12521047 AB - The penetration depth of low-energy heavy ions in botanic samples was detected with a new transmission measurement. In the measurement, highly oriented pyrolytic graphite (HOPG) pieces were placed behind the botanic samples with certain thickness. During the irradiation of heavy ions with energy of tens of keV, the energetic particles transmitted from those samples were received by the HOPG pieces. After irradiation, scanning tunneling microscope (STM) was applied to observe protrusion-like damage induced by these transmitted ions on the surface of the HOPG. The statistical average number density of protrusions and the minimum transmission rate of the low-energy heavy ions can be obtained. The detection efficiency of the new method for low-energy heavy ions was about 0.1-1 and the background in the measurement can be reduced to as low as 1.0 x 10(8) protrusions/cm2. With this method, the penetration depth of the energetic particles was detected to be no less than 60 micrometers in kidney bean slices when the slices were irradiated by 100 keVAr+ ion at the fluence of 5 x 10(16) ions/cm2. c2002 Elsevier Science Ltd.

All carbonaceous chondritic microclasts are made of a fine-grained phyllosilicate-rich matrix supporting a variety of minerals such as olivine, pyroxene, spinel, iron oxides, iron-nickel sulfides, and calcium carbonates. Such a mineralogy is typical of chondritic C2 matter. Half of the carbonaceous chondritic microclasts are tochilinite-rich, and have been tentatively called CM2 microclasts. The other half are magnetite-rich, and have been tentatively called CR2 microclasts. The absence of a correlation between the CM2/CR2 ratio in carbonaceous chondritic microclasts and in numerous millimeter-sized clasts found in the same sections argues for carbonaceous chondritic microclasts being true micrometeorites rather than fragments of larger objects. Dynamical simulations show that it is possible for asteroidal dust to encounter Vesta (the howardite's putative parent-asteroid) at velocity low enough (<1 km.s (super -1) ) to prevent fragmentation. Because the micrometeorite flux in the inner Solar System has been decreasing with time, we argue that carbonaceous chondritic microclasts have been trapped in Vesta's regolith early in the history of the Solar System and are fossil micrometeorites. Because both microclasts and clasts found in howardites are related to C2 chondritic matter, we propose that C2 matter represents the bulk, or at least a significant fraction of the primordial howardite parent-asteroid. Considering the abundance of C2 matter among fossil micrometeorites, we speculate that the C2 fossil micrometorites are the so far unidentified agent of the late chondritic veneer that endowed the Earth's mantle with an excess of siderophile elements relative to the contents predicted by the core-mantle separation models. The discovery that C2 fossil micrometeorites are similar to C2 modern Antarctic micrometeorites supports recent models proposing a micrometeoritic origin for the Earth's oceans and volatile species.

New Os data for the 89 Ma Gorgona Island, Colombia komatiites indicate that these lavas are also variably enriched in (super 186) Os and (super 187) Os, with (super 186) Os/ (super 188) Os ranging between 0.1198397+ or -22 and 0.1198470+ or -38, and with gamma (sub Os) correspondingly ranging from +0.15 to +4.4. These data define a linear trend that converges with the previously reported linear trend generated from data for modern Hawaiian picritic lavas and a sample from the ca. 251 Ma Siberian plume, to a common component with a (super 186) Os/ (super 188) Os of approximately 0.119870 and gamma (sub Os) of +17.5. The convergence of these data to this Os isotopic composition may imply a single ubiquitous source in the Earth's interior that mixes with a variety of different mantle compositions distinguished by variations in gamma (sub Os) . The (super 187) Os- and (super 186) Os-enriched component may have been generated via early crystallization of the solid inner core and consequent increases in Pt/Os and Re/Os in the liquid outer core, with time leading to suprachondritic (super 186) Os/ (super 188) Os and gamma (sub Os) in the outer core. The presence of Os from the outer core in certain portions of the mantle would require a mechanism that could transfer Os from the outer core to the lower mantle, and thence to the surface. If this is the process that generated the isotopic enrichments in the mantle sources of these plume-derived systems, then the current understanding of solid metal-liquid metal partitioning of Pt, Re and Os requires that crystallization of the inner core began prior to 3.5 Ga. Thus, the Os isotopic data reported here provide a new source of data to better constrain the timing of inner core formation, complementing magnetic field paleo-intensity measurements as data sources that constrain models based on secular cooling of the Earth.

Noble-gas analysis was performed on two samples and the results showed that primordial noble gases are abundant and solar noble gases are absent in the samples of carbonate-rich lithology. The concentrations of Ne-A2 and -E in both samples are at the maximum level observed for CI and CM chondrites, suggesting high abundances of presolar diamonds and SiC/graphite, respectively. The cosmic-ray exposure age cannot be determined precisely, because the shielding depth of our Tagish Lake samples is unknown, but the minimum exposure age was determined to be 5.5+ or -0.7 Myr on the basis of cosmogenic (super 21) Ne concentrations and the highest (super 21) Ne production rate. X-ray and electron-microscopic study showed that the carbonate-rich lithology is dominated by loosely packed porous matrix that consists mainly of fine-grained saponite and ferromagenesian carbonate. The matrix contains very few chondrules, but many fine-grained clasts having angular shape with longest dimensions up to 1 mm. The clasts differ from host matrix in both texture and mineralogy. They are massive, compacted material with porosity much lower than matrix and contain abundant magnetite and a coherent intergrowth of serpentine and saponite that is rare in matrix. The presence of texturally and mineralogically distinct clasts indicates that the carbonate-rich lithology is a breccia, but the absence of solar noble gases and impact-induced deformational features in host matrix distinguish it from an asteroid regolith breccia. Our results instead indicate that it is an accretionary breccia formed by simultaneous accretion of diverse objects in a massive dust cloud. The clasts often enclose chondrules and anhydrous silicate fragments such as low-iron-manganese-enriched olivines. This observation and their highly compacted, angular morphology suggests that the clasts derive from earlier-formed chondritic materials which have experienced compression and fragmentation due to mild impacts and from which they were excavated and incorporated into the final rock. It is thus suggested that, in the course of planetesimal formation, agglomeration and disagglomeration of small parent bodies occurred repeatedly in a dense dust cloud where solar wind from the infant sun was shielded. The fine-grained ferromagnesian carbonates must have precipitated from aqueous solutions after the assembly of the Tagish Lake asteroid from recycled materials from previous bodies, because the carbonates coat the surfaces of pores and fill in veins in the clasts.

Satellite models show large secular variations in the center of the Indian Ocean where there are few island geomagnetic observatories. This paper investigates marine geomagnetic measurements to see if they give more information about secular variations in this area. Between 1960 and 1988 there were more than 70 port-to-port cruises with ships towing proton precession magnetometers in the Indian Ocean. Change in field intensity from one cruise to another provides new information about the secular variation in this part of the world. Several methods were investigated to determine this change from the ship's data. Observing the change on closely parallel or crossing tracks provides an estimate of this change. These results indicate that there are short time and distance scales of secular variation in the Indian Ocean which have not been accounted for in geomagnetic field models.

Y-86029 is a breccia consisting of a variety of clasts, and abundant secondary minerals including coarse-and fine-grained phyllosilicates, Fe-Ni sulfides, carbonates, and magnetite. There are no chondrules, but a few anhydrous olivine-rich grains are present within a very fine-grained phyllosilicate-rich matrix. Analyses of 14 thermally mobile trace elements suggest that Y-86029 experienced moderate, open-system thermal metamorphism. Comparison with data for other heated carbonaceous chondrites suggests metamorphic temperatures of 500-600 degrees C for Y-86029. This is apparent petrographically, in partial dehydration of phyllosilicates to incompletely re-crystallized olivine. This transformation appears to proceed through "intermediate" highly-disordered "poorly crystalline" phases consisting of newly formed olivine and residual desiccated phyllosilicate and their mixtures. Periclase is also present as a possible heating product of Mg-rich carbonate precursors. Y-86029 shows unusual textures rarely encountered in carbonaceous chondrites. The periclase occurs as unusually large Fe-rich clasts (300-500 mu m). Fine-grained carbonates with uniform texture are also present as small (10-15 mu m in diameter), rounded to sub-rounded "shells" of ankerite/siderite enclosing magnetite. These carbonates appear to have formed by low temperature aqueous alteration at specific thermal decomposition temperatures consistent with thermodynamic models of carbonate formation. The fine and uniform texture suggests crystallization from a fluid circulating in interconnected spaces throughout entire growth. One isolated aggregate in Y-86029 also consists of a mosaic of polycrystalline olivine aggregates and sulfide blebs typical of shock-induced melt recrystallization. Except for these unusual textures, the isotopic, petrologic and chemical characteristics of Y-86029 are quite similar to those of Y-82162, the only other heated CI-like chondrite known. They were probably derived from similar asteroids rather than one asteroid, and hence may not necessarily be paired.

However, the majority of the partitioning experiments have been conducted with trace elements doped at levels that are orders of magnitude higher than measured in iron meteorites. Concern about Henry's Law and the unnatural doping levels have been cited as one reason that two recent iron meteorite studies have dismissed the experimental partition coefficients in their modeling. Using laser ablation ICP-MS analysis, this study reports experimentally determined solid metal-liquid metal trace element partition coefficients from runs doped down to the levels occurring in iron meteorites. The analyses for 12 trace elements (As, Co, Cr, Cu, Ga, Ge, Ir, Os, Pd, Pt, Re, and W) show no deviations from Henry's Law, and these results support decades of experimental work in which the partition coefficients were assumed to be independent of trace element concentration. Further, since our experiments are doped with natural levels of trace elements, the partitioning results are directly applicable to iron meteorites and should be used when modeling their crystallization. In contrast, our new Ag data are inconsistent with previous studies, suggesting the high Ag-content in previous studies may have influenced the measured Ag partitioning behavior.

Trapped (super 36) Ar concentration amounts to 6X10 (super -6) cc STP/g, which is higher than that of Ningqiang host by a factor of three. Light HF-HCL etching of the dark inclusion removed 86, 73, and 64% of the primordial (super 36) Ar, (super 84) Kr, and (super 132) Xe, respectively. Thus, the majority of the noble gases in this inclusion are located in very acid-susceptive material. Based on the elemental composition, the noble gases lost from the dark inclusion during the acid-treatments are Ar-rich, and the noble gases remaining in the inclusion are Q and HL gases. Transmission electron microscopy showed that the acid treatments removed thin Si, Mg, and Fe-rich amorphous rims present around small olivine and pyroxene grains in the dark inclusion, suggesting that the Ar-rich gases reside in the amorphous layers. A possible origin of the Ar-rich gases is the acquisition of noble-gas ions with a composition fractionated relative to solar abundance favoring the heavy elements by the effect of incomplete ionization under plasma conditions at 8000 K electron temperature.

The DI contains two lithologies. The first, lithology A, contains micron-sized olivine and pyroxene grains rimmed by amorphous materials with compositions similar to the underlying crystalline grains. The second, lithology B, appears to preserve the mineralogy of lithology A before formation of the amorphous rims. Overall, the Ningqiang DI appears to record the following processes: 1) formation (condensation and Fe-enrichment) of olivine crystals in the nebula with compositions of Fo (sub 42-62) ; 2) irradiation, resulting in amorphitization of the olivine and pyroxene to varying degrees; 3) partial annealing, resulting in formation of fairly large, euhedral olivine and pyroxene grains with remnant amorphous sharply-bounded rims; 4) in some cases, prolonged annealing, resulting in the formation of microcrystalline olivine or pyroxene rims. The latter annealing would have been a natural consequence of irradiation near the critical temperature for olivine; and 5) mixture of the above materials (lithology A) with nebular condensate high-Ca pyroxene and olivine, which escaped nebular processing, to become lithology B. We suggest that the amorphous rims in lithology A formed in an energetic solar event such as a bi-polar outflow or FU-orionis flare.

The AMSR-E instrument provides a potentially improved soil moisture sensing capability over previous spaceborne radiometers such as the Scanning Multichannel Microwave Radiometer and Special Sensor Microwave/Imager due to its combination of low frequency and higher spatial resolution (approximately 60 km at 6.9 GHz). The AMSR-E soil moisture retrieval approach and its implementation are described in this paper. A postlaunch validation program is in progress that will provide evaluations of the retrieved soil moisture and enable improved hydrologic applications of the data. Key aspects of the validation program include assessments of the effects on retrieved soil moisture of variability in vegetation water content, surface temperature, and spatial heterogeneity. Examples of AMSR-E brightness temperature observations over land are shown from the first few months of instrument operation, indicating general features of global vegetation and soil moisture variability. The AMSR-E sensor calibration and extent of radio frequency interference are currently being assessed, to be followed by quantitative assessments of the soil moisture retrievals. The AMSR-E instrument was developed by the National Space Development Agency of Japan (NASDA) and provided to the U.S. National Aeronautics and Space Administration. A similar instrument was launched in December 2002 on NASDA's ADEOS-II satellite.

The large-scale sea ice properties are highly sensitive to sea ice dynamics. With the inclusion of resistance to shear stress, VP captures the major observed sea ice drift features and improves the simulations of sea ice concentrations, thickness, and export through Fram Strait relative to CF. GM significantly improves the simulation of vertical temperature distributions in the Southern Ocean, although it leads to a dramatic reduction of Antarctic sea ice cover. Two composite experiments with the best parameterizations are investigated. The atmospheric responses associated with sea ice changes are discussed. (mod. journ. abst.)

Extreme conditions prevailed including freezing temperatures, low atmospheric pressure, high evaporation/sublimation rates, and liquid water reservoirs locked in aquifers below a thick cryosphere. Although many of the Martian paleolakes display evidence of a short period of activity consistent with these conditions, others display clear evidence of lifetimes ranging from 10 (super 4) to 10 (super 5) years. The discovery of young seeping processes in impact craters and pole-facing valley slopes along with young volcanic activity raise questions about the conditions and limitations of liquid water flow and potential lacustrine activity today on Mars. Current climate models show that in today's conditions there exist regions on Mars of sols above the triple point and below boiling point of water that could provide hydrogeological conditions comparable to these of the Antarctic Dry Valley lakes (with the exception of the atmosphere pressure). The locations of the most recent Martian paleolakes are correlated with these regions. Throughout the history of Mars, lakes generated diversified environments, which could have provided potential habitats for life. The recent discovery of young energy sources from volcanism and the potential for liquid water reinforces the possibility of extant life on Mars, and suggests recent ponds and ancient paleolakes as primary targets for rover and sample return missions.

The globally complete precipitation fields reveal coherent bands of anomalies that extend from the tropics to the polar regions. El Nino-precipitation relationships were analyzed during the six strongest events from 1979 to 2001. El Ninos were defined based on the zonal contrast in rainfall in the equatorial Pacific, and seasons of precipitation evolution (pre- onset, onset, peak, decay, and postdecay) were identified. Areas with a consistent El Nino-precipitation relationship were determined based on this unique definition of El Nino and season of year. The latter analysis confirms previous studies and suggests other areas of significant signal over the oceans (Gulf of Alaska). The former analysis reveals subtle shifts in tropical rainfall from onset to decay, namely negative anomalies moving from the Maritime Continent and South Pacific to the north tropical Pacific and positive anomalies from the central equatorial Pacific southeastward. These distributions of tropical convection appear to be connected to extratropical precipitation anomalies through meridional atmospheric circulations, concentrated in the eastern Indian Ocean sector during onset and in the Pacific sector during decay. The Yangtze River basin, which is known to flood during El Nino, is affected during the entire evolution. JF - Journal of Geophysical Research. D.

Time series of rainfall estimates from the Tropical Rainfall Measuring Mission (TRMM) Precipitation Radar (PR) over the tropical oceans show marked differences with estimates from two TRMM Microwave Imager (TMI) passive microwave algorithms. We show that path-integrated attenuation derived from the effects of precipitation on the radar return from the ocean surface exhibits interannual variability that agrees closely with the TMI time series. Our analysis of discrepancies between the PR rainfall and attenuation suggests that uncertainty in the assumed drop size distribution and associated attenuation/reflectivity/rainfall relationships inherent in single-frequency radar methods is a serious issue for studies of interannual variability.

In contrast, preliminary trials in Florida greenhouses failed to achieve the level of disease suppression reported in the literature for Canadian studies. A series of greenhouse experiments were conducted in Florida to determine the factors involved in reducing the effectiveness of silicon amendments for PM suppression on cucumber. Three horticultural practices (cultivar, nutrient solution formula, and rooting medium) and two environmental factors (light intensity and temperature) were tested in combination with silicon amendments for their effects on the suppression of PM on cucumber. When plants were irrigated with a standard nutrient solution amended with potassium silicate at 0 mg/liter, the cucumber cv. Vetomil was found to be resistant and cvs. Corona, Cilia, Farbio, and Toska were found to be susceptible to PM. Susceptible cultivars irrigated with potassium silicate at 100, 150, or 200 mg/liter exhibited a slight but statistically significant reduction in PM over the course of a 49-day trial. Although PM in the cultivar trial was slightly lower in treatments with added silicon, disease suppression with silicon was not commercially useful because it failed to increase fruit yields. Nutrient solution formula, rooting medium, and light intensity had no effects on the levels of PM suppression, regardless of whether plants were irrigated with potassium silicate at 0 or 100 mg/liter. Temperature was found to act in a synergistic manner with silicon. The greatest effect of temperature on PM suppression was observed at 20 degree C in which cucumber plants, irrigated with silicon at 100 mg/liter, exhibited significant reductions in the numbers of PM colonies per leaf. Disease suppression by silicon was observed at 25 and 30 degree C, but the magnitude of the disease suppression was significantly lower than when plants were maintained at 20 degree C. The effect of temperature on PM suppression by silicon may explain the difference in results between previous experiments in Canada, where greenhouse temperatures averaged 20 to 25 degree C, and the current study in Florida, where greenhouse temperatures averaged 24 to 32 degree C.

The model results show that when CO sub(2) in the atmosphere is doubled, a strong ground warming occurs in the TP. Two regions within it with the largest warming are in the eastern TP (region I) and along the southwestern and western slopes (region II). Moreover, in region I the ground warming in the winter half year is stronger than that in the summer half year, but in region II the warming difference between the seasons becomes opposite to that in region I, i.e., the warming is strong in the summer half year and weak in the winter half year. There are indications that the summer monsoon enhances but the winter monsoon weakens when CO sub(2) is doubled. A strong elevation dependency of ground warming is found in region I for the winter half year, and in region II for both winter and summer half years at elevations below 5 km. The simulated characteristics of ground warming in the TP are consistent with the observations. In region I, when CO sub(2) is doubled, the cloud amount increases at lower elevations and decreases at higher elevation for the winter half year. As a consequence, at lower elevations the short wave solar radiation absorbed at the surface declines, and the downward long wave flux reaching the surface enhances; on the other hand, at higher elevations the surface solar radiation flux increases and the surface infrared radiation flux shows a more uniform increase. The net effect of the changes in both radiation fluxes is an enhanced surface warming at higher elevations, which is the primary cause of the elevation dependency in the surface warming. In the summer half year the cloud amount reduces as a result of doubling CO sub(2) in region I for all elevations, and there is no elevation dependency detected in the ground warming. Furthermore, there is little snow existing in region I for both summer and winter half years, and the impact of snow-albedo feedback is not significant. In region II, although the changes in the cloud amount bear a resemblance to those in region I, the most significant factor affecting the surface energy budget is the depletion of the snow cover at higher elevations, which leads to a reduction of the surface albedo. This reduction in turn leads to an enhancement in the solar radiation absorbed in the surface. The snow-albedo feedback mechanism is the most essential cause of the elevation dependency in the surface warming for region II.

The model is able to capture a number of important aspects of the space-time spectrum of rain-rate variability, including the interdependence of time and space scales of variability. Four parameters must be specified in the model. Sets of parameters have been obtained that fit the statistics of radar-derived rain rates over the eastern tropical Atlantic (from GATE) and the western tropical Pacific (from TOGA COARE). The model predicts that there is an optimal averaging time for gauge data when gauge averages are compared to average satellite rain-rates for a specified area around the gauge. The optimal averaging time ranges from minutes to days as the diameter of the area around the gauge is extended from 2 km to 200 km. The optimal averaging time shrinks as more gauges are added to the area viewed by the satellite, but the model suggests that even over fairly dense gauge networks it is necessary to compare averages of several hundred satellite overflights in order to bring the comparison error down to the 10% level. The possibility that comparisons of gauge data with satellite averages might be improved by weighting the gauge data differently depending on how close the gauge data are in time to the satellite overflights is investigated, and it is found that in some cases the variance of the comparison error can be reduced by a factor of two by using optimal time- dependent weighting.

Each deployment started from Broomfield, Colorado, with bases in Churchill, Canada, and on most deployments, Thule Air Base, Greenland. Nadir and zenith lidar O sub(3) measurements were combined with in situ O sub(3) measurements to produce vertically continuous O sub(3) profiles from near the surface to above the tropopause. Potential vorticity (PV) distributions along the flight track were obtained from several different meteorological analyses. Ozone, aerosol, and PV distributions were used together to identify the presence of pollution plumes and stratospheric intrusions. Ozone was found to increase in the middle free troposphere (4-6 km) at high latitudes (60 degree -85 degree N) by an average of 4.6 ppbv/mo (parts per billion by volume per month) from about 54 ppbv in early February to over 72 ppbv in mid-May. The average aerosol scattering ratios at 1064 nm in the same region increased rapidly at an average rate of 0.36/mo from about 0.38 to over 1.7. Ozone and aerosol scattering were highly correlated over the entire field experiment, and PV and beryllium ( super(7)Be) showed no significant positive trend over the same period. The primary cause of the observed O sub(3) increase in the mid troposphere at high latitudes was determined to be the photochemical production of O sub(3) in pollution plumes with less than 20% of the increase from stratospherically-derived O sub(3).

The well-characterized external embryological development of the frog allows simple access to specific developmental stages by rapid visual inspection. We will conduct an insertional mutagenesis screen in Xenopus using a gene-trap vector containing a splice acceptor (SA) sequence followed by a marker gene, green fluorescent protein (GFP). Since the marker gene lacks a promoter, it can only be transcribed and translated if it integrates properly into an exon or intron of an endogenous gene. Expression of the bright GFP following insertional mutagenesis is visible in living embryos. In addition, since the trapped (and prospectively mutated) gene is always marked by GFP, one can easily distinguish between embryos carrying the mutation from ones that do not. We will use visual inspection to screen for tadpoles with insertions of the GFP- transgene into genes expressed during otic development. We propose the following specific aims: (1) We will use insertional mutagenesis to generate stable GFP- expressing lines of the true diploid, Xenopus tropicalis, carrying transgenes expressed in the otic regions. These stable lines will be used for studying the mutant phenotype generated by the insertion. (2) We will clone and characterize otic genes into which the GFP transgene has inserted. (3) We will characterize the development of the tissue in which the GFP-transgene is expressed using fluorescence video microscopy in live heterozygotic embryos or in fixed tissues using immunohistochemistry (both light and EM). Results of these investigations will provide essential knowledge of the specific genes involved in otic development as well as mutant lines that can be used for future studies of the specific function of these genes in acoustic or vestibular functions.

AN - 75770340; 14552356 AB - Sound travelling through a gas propagates at different speeds and its intensity attenuates to different degrees depending upon the composition of the gas. Theoretically, a real-time gaseous composition sensor could be based on measuring the sound speed and the acoustic attenuation. To this end, the speed of sound was modelled using standard relations, and the acoustic attenuation was modelled using the theory for vibrational relaxation of gas molecules. The concept for a gas composition sensor is demonstrated theoretically for nitrogen-methane-water and hydrogen-oxygen-water mixtures. For a three-component gas mixture, the measured sound speed and acoustic attenuation each define separate lines in the composition plane of two of the gases. The intersection of the two lines defines the gas composition. It should also be possible to use the concept for mixtures of more than three components, if the nature of the gas composition is known to some extent.

AN - 73685402; 14503525 AB - Quick response to different impacts and easy measurement make the luminescent systems of luminous bacteria an object convenient for application in various fields. Cloning of gene luminescence in different organisms is currently used to study both the survival of microbial cells and the effect of different factors on their metabolic activity, including the environment. A primary test-object in estimating bacteriological contamination of water bodies, Escherichia coli, can be conveniently used as an indicator of bactericidal properties of aquatic ecosystems. The application of Escherichia coli Z905/pPHL7 (lux+) as a marker microorganism can facilitate monitoring the microbiological status of closed biocenoses, including systems with higher organisms. The investigation of various parameters of microecosystems (carbon nutrition type, concentrations of inorganic ions and toxic compounds) shows that the recombinant strain E. coli Z905/pPHL7 can be effectively used as a marker. c2003 COSPAR.

AN - 73685304; 14503500 AB - The unprecedented challenges of creating Biosphere 2, the world's first laboratory for biospherics, the study of global ecology and long-term closed ecological system dynamics, led to breakthrough developments in many fields, and a deeper understanding of the opportunities and difficulties of material closure. This paper will review accomplishments and challenges, citing some of the key research findings and publications that have resulted from the experiments in Biosphere 2. Engineering accomplishments included development of a technique for variable volume to deal with pressure differences between the facility and outside environment, developing methods of atmospheric leak detection and sealing, while achieving new standards of closure, with an annual atmospheric leakrate of less than 10%, or less than 300 ppm per day. This degree of closure permitted detailed tracking of carbon dioxide, oxygen, and trace gases such as nitrous oxide and ethylene over the seasonal variability of two years. Full closure also necessitated developing new approaches and technologies for complete air, water, and wastewater recycle and reuse within the facility. The development of a soil-based highly productive agricultural system was a first in closed ecological systems, and much was learned about managing a wide variety of crops using non-chemical means of pest and disease control. Closed ecological systems have different temporal biogeochemical cycling and ranges of atmospheric components because of their smaller reservoirs of air, water and soil, and higher concentration of biomass, and Biosphere 2 provided detailed examination and modeling of these accelerated cycles over a period of closure which measured in years. Medical research inside Biosphere 2 included the effects on humans of lowered oxygen: the discovery that human productivity can be maintained with good health with lowered atmospheric oxygen levels could lead to major economies on the design of space stations and planetary/lunar settlements. The improved health resulting from the calorie-restricted but nutrient dense Biosphere 2 diet was the first such scientifically controlled experiment with humans. The success of Biosphere 2 in creating a diversity of terrestrial and marine environments, from rainforest to coral reef, allowed detailed studies with comprehensive measurements such that the dynamics of these complex biomic systems are now better understood. The coral reef ecosystem, the largest artificial reef ever built, catalyzed methods of study now being applied to planetary coral reef systems. Restoration ecology advanced through the creation and study of the dynamics of adaptation and self-organization of the biomes in Biosphere 2. The international interest that Biosphere 2 generated has given new impetus to the public recognition of the sciences of biospheres (biospherics), biomes and closed ecological life systems. The facility, although no longer a materially-closed ecological system, is being used as an educational facility by Columbia University as an introduction to the study of the biosphere and complex system ecology and for carbon dioxide impacts utilizing the complex ecosystems created in Biosphere '. The many lessons learned from Biosphere 2 are being used by its key team of creators in their design and operation of a laboratory-sized closed ecological system, the Laboratory Biosphere, in operation as of March 2002, and for the design of a Mars on Earth(TM) prototype life support system for manned missions to Mars and Mars surface habitats. Biosphere 2 is an important foundation for future advances in biospherics and closed ecological system research. c2003 Published by Elsevier Science Ltd on behalf of COSPAR.

AN - 73675597; 14503510 AB - An initial experiment in the Laboratory Biosphere facility, Santa Fe, New Mexico, was conducted May-August 2002 using a soil-based system with light levels (at 12 h per day) of 58-mol m-2 d-1. The crop tested was soybean, cultivar Hoyt, which produced an aboveground biomass of 2510 grams. Dynamics of a number of trace gases showed that methane, nitrous oxide, carbon monoxide, and hydrogen gas had initial increases that were substantially reduced in concentration by the end of the experiment. Methane was reduced from 209 ppm to 11 ppm, and nitrous oxide from 5 ppm to 1.4 ppm in the last 40 days of the closure experiment. Ethylene was at elevated levels compared to ambient during the flowering/fruiting phase of the crop. Soil respiration from the 5.37 m2 (1.46 m3) soil component was estimated at 23.4 ppm h-1 or 1.28 g CO2 h-1 or 5.7 g CO2 m-2 d-1. Phytorespiration peaked near the time of fruiting at about 160 ppm h-1. At the height of plant growth, photosynthesis CO2 draw down was as high as 3950 ppm d-1, and averaged 265 ppm h-1 (whole day averages) during lighted hours with a range of 156-390 ppm h-1. During this period, the chamber required injections of CO2 to continue plant growth. Oxygen levels rose along with the injections of carbon dioxide. Upon several occasions, CO2 was allowed to be drawn down to severely limiting levels, bottoming at around 150 ppm. A strong positive correlation (about 0.05 ppm h-1 ppm-1 with r2 about 0.9 for the range 1000-5000 ppm) was observed between atmospheric CO2 concentration and the rate of fixation up to concentrations of around 8800 ppm CO2. c2003 COSPAR.

AN - 73672447; 14503518 AB - The effect of elevated temperatures of 35 and 45 degrees C (at the intensities of photosynthetically active radiation 322, 690 and 1104 micromoles m-2 s-1) on the photosynthesis, respiration, and qualitative and quantitative composition of the volatiles emitted by wheat (Triticum aestuvi L., cultivar 232) crops was investigated in growth chambers. Identification and quantification of more than 20 volatile compounds (terpenoids--alpha-pinene, delta 3 carene, limonene, benzene, alpha- and trans-caryophyllene, alpha- and gamma-terpinene, their derivatives, aromatic hydrocarbons, etc.) were conducted by gas chromatograph/mass spectrometry. Under light intensity of 1104 micromoles m-2 s-1 heat resistance of photosynthesis and respiration increased at 35 degrees C and decreased at 45 degrees C. The action of elevated temperatures brought about variations in the rate and direction of the synthesis of volatile metabolites. The emission of volatile compounds was the greatest under a reduced irradiation of 322 micromoles m-2 s-1 and the smallest under 1104 micromoles m-2 s-1 at 35 degrees C. During the repair period, the contents and proportions of volatile compounds were different from their initial values, too. The degree of disruption and the following recovery of the functional state depended on the light intensity during the exposure to elevated temperatures. The investigation of the atmosphere of the growth chamber without plants has revealed the substances that were definitely technogenic in origin: tetramethylurea, dimethylsulfide, dibutylsulfide, dibutylphthalate, and a number of components of furan and silane nature. c2003 COSPAR.

AN - 73672408; 14503501 AB - Sustainability is one of the most important criteria in the creation and evaluation of human life support systems intended for use during long space flights. The common feature of biological and physicochemical life support systems is that basically they are both catalytic. But there are two fundamental properties distinguishing biological systems: 1) they are auto-catalytic: their catalysts--enzymes of protein nature--are continuously reproduced when the system functions; 2) the program of every process performed by enzymes and the program of their reproduction are inherent in the biological system itself--in the totality of genomes of the species involved in the functioning of the ecosystem. Actually, one cell with the genome capable of the phenotypic realization is enough for the self-restoration of the function performed by the cells of this species in the ecosystem. The continuous microalgal culture of Chlorella vulgaris was taken to investigate quantitatively the process of self-restoration in unicellular algae population.

AN - 73669824; 14503516 AB - The processes resulting from the introduction of the tranagenic microorganism (TM) E. coli Z905/pPHL7 into aquatic microcosms have been modeled experimentally. It has been shown that the TM E. coli is able to adapt to a long co-existence with indigenous heterotrophic microflora in variously structured microcosms. In more complex microcosms the numerical dynamics of the introduced E. coli Z905/pPHL7 population is more stable. In the TM populations staying in the microcosms for a prolonged time, changes are recorded in the phenotypic expression of plasmid genes (ampicillin resistance and the luminescence level) and chromosome genes (morphological and physiological traits). However, in our study microcosms, the recombinant plasmid persisted in the TM cells for 6 years after the introduction, and as the population adapts to the conditions of the microcosms, the efficiency of the cloned gene expression in the cells is restored. In the microcosms with high microalgal counts (10(7) cells/ml), cells with a high threshold of sensitivity to ampicillin dominate in the population of the TM E. coli Z905/pPHL7. c2003 COSPAR.

AN - 73669739; 14503502 AB - The parallels between the challenges facing bioregenerative life support in artificial closed ecological systems and those in our global biosphere are striking. At the scale of the current global technosphere and expanding human population, it is increasingly obvious that the biosphere can no longer safely buffer and absorb technogenic and anthropogenic pollutants. The loss of biodiversity, reliance on non-renewable natural resources, and conversion of once wild ecosystems for human use with attendant desertification/soil erosion, has led to a shift of consciousness and the widespread call for sustainability of human activities. For researchers working on bioregenerative life support in closed systems, the small volumes and faster cycling times than in the Earth's biosphere make it starkly clear that systems must be designed to ensure renewal of water and atmosphere, nutrient recycling, production of healthy food, and safe environmental methods of maintaining technical systems. The development of technical systems that can be fully integrated and supportive of living systems is a harbinger of new perspectives as well as technologies in the global environment. In addition, closed system bioregenerative life support offers opportunities for public education and consciousness changing of how to live with our global biosphere. c2003 COSPAR.

AN - 73668675; 14503519 AB - Waste technologies for Mars missions have been analyzed, considering equivalent system mass and interface loads. Storage or dumping seems most appropriate for early missions with low food closure. Composting or other treatment of inedible biomass in a bioreactor seems most attractive for moderate food closure (50-75%). Some form of physicochemical oxidation of the composted residue might be needed for increased food closure, but oxidation of all waste does not seem appropriate due to excess of production of carbon dioxide over demand. More comprehensive analysis considering interfaces with other mission systems is needed. In particular, in-situ resource utilization is not considered, and might provide resources more cheaply than waste processing. c2003 COSPAR. Published by Elsevier Science Ltd. All rights reserved.

AN - 73668505; 14503508 AB - The C.E.B.A.S.-Minimodule (Closed Equilibrated Biological Aquatic System) is a space qualified aquatic microcosm of 8.6 liters volume of water. Several aquatic species can be reared in parallel. Based on its characteristics (closed system, highly standardized, testruns longer than 4 weeks are possible, organisms of different trophic levels can be investigated) an improved module (C.B.R.U.=Closed Biological Research Unit) is under development for scientific and commercial use in ecotoxicology. In a two year project named AToxMss (Aquatic EcoToxicology in a Multispecies System) this goal can be reached. AToxMss is a R&D project of an industry team and two teams of the University of Bremen, funded by industry (OHB-System AG) and the state of Bremen, Germany. Three project phases are already completed: The parameter determination to indicate potential impact of chemicals on biological systems, the selection of test substances, as well as the manufacturing of 3 functional modules, each verified for use in ecotoxicological research. The next phase starts with a series of test runs calibrating the system by using well known toxic substances and chemicals. Published by Elsevier Science Ltd on behalf of COSPAR.

The dynamic range of this model covers all magnetic activity levels specified by integer values of the Kp magnetic index. We present comparisons of the measured dose observed on the space shuttle during the August 1989 solar proton event with the dose computed from solar particles predicted to be allowed through the magnetosphere to the space shuttle position. We find a one-to-one correspondence between the portion of the orbit predicted to be subjected to solar protons and the portion of the orbit where solar particle dose measurements were obtained. c2003 COSPAR.

AN - 73666622; 14503509 AB - An experimental model of a biological life support system was used to evaluate qualitative and quantitative parameters of the internal mass exchange. The photosynthesizing unit included the higher plant component (wheat and radish), and the heterotrophic unit consisted of a soil-like substrate, California worms, mushrooms and microbial microflora. The gas mass exchange involved evolution of oxygen by the photosynthesizing component and its uptake by the heterotroph component along with the formation and maintaining of the SLS structure, growth of mushrooms and California worms, human respiration, and some other processes. Human presence in the system in the form of "virtual human" that at regular intervals took part in the respirative gas exchange during the experiment. Experimental data demonstrated good oxygen/carbon dioxide balance, and the closure of the cycles of these gases was almost complete. The water cycle was nearly 100% closed. The main components in the water mass exchange were transpiration water and the watering solution with mineral elements. Human consumption of the edible plant biomass (grains and roots) was simulated by processing these products by a unique physicochemical method of oxidizing them to inorganic mineral compounds, which were then returned into the system and fully assimilated by the plants. The oxidation was achieved by "wet combustion" of organic biomass, using hydrogen peroxide following a special procedure, which does not require high temperature and pressure. Hydrogen peroxide is produced from the water inside the system. The closure of the cycle was estimated for individual elements and compounds. Stoichiometric proportions are given for the main components included in the experimental model of the system. Approaches to the mathematical modeling of the cycling processes are discussed, using the data of the experimental model. Nitrogen, as a representative of biogenic elements, shows an almost 100% closure of the cycle inside the system. The proposed experimental model of a biological system is discussed as a candidate for potential application in the investigations aimed at creating ecosystems with largely closed cycles of the internal mass exchange. The formation and maintenance of sustainable cycling of vitally important chemical elements and compounds in biological life support systems (BLSS) is an extremely pressing problem. To attain the stable functioning of biological life support systems (BLSS) and to maintain a high degree of closure of material cycles in than, it is essential to understand the character of mass exchange processes and stoichiometnc proportions of the initial and synthesized components of the system. c2003 COSPAR.

AN - 73663399; 14503520 AB - Research and design of subsurface flow wetland wastewater treatment systems for a ground-based experimental prototype Mars Base facility has been carried out, using a subsurface flow approach. These systems have distinct advantages in planetary exploration scenarios: they are odorless, relatively low-labor and low-energy, assist in purification of water and recycling of atmospheric CO2, and will support some food crops. An area of 6-8 m2 may be sufficient for integration of wetland wastewater treatment with a prototype Mars Base supporting 4-5 people. Discharge water from the wetland system will be used as irrigation water for the agricultural crop area, thus ensuring complete recycling and utilization of nutrients. Since the primary requirements for wetland treatment systems are warm temperatures and lighting, such bioregenerative systems may be integrated into early Mars base habitats, since waste heat from the lights may be used for temperature maintenance in the human living environment. "Wastewater gardens (TM)" can be modified for space habitats to lower space and mass requirements. Many of its construction requirements can eventually be met with use of in-situ materials, such as gravel from the Mars surface. Because the technology requires little machinery and no chemicals, and relies more on natural ecological mechanisms (microbial and plant metabolism), maintenance requirements are minimized, and systems can be expected to have long operating lifetimes. Research needs include suitability of Martian soil and gravel for wetland systems, system sealing and liner options in a Mars Base, and wetland water quality efficiency under varying temperature and light regimes. c2003 COSPAR.

AN - 73663254; 14503503 AB - The mathematical modeling of ecosystems has contributed much to the understanding of the dynamics of such systems. Ecosystems can include not only the natural variety, but also artificial systems designed and controlled by humans. These can range from agricultural systems and activated sludge plants, down to mesocosms, microcosms, and aquaria, which may have practical or research applications. Some purposes may require the design of systems that are completely closed, as far as material cycling is concerned. In all cases, mathematical modeling can help not only to understand the dynamics of the system, but also to design methods of control to keep the system operating in desired ranges. This paper reviews mathematical modeling relevant to the simulation and control of closed or semi-closed artificial ecosystems designed for biological production and recycling in applications in space.

AN - 73658046; 12971414 AB - The lens epithelium is the initiation site for the development of radiation induced cataracts. Radiation in the cortex and nucleus interacts with proteins, while in the epithelium, experimental results reveal mutagenic and cytotoxic effects. It is suggested that incorrectly repaired DNA damage may be lethal in terms of cellular reproduction and also may initiate the development of mutations or transformations in surviving cells. The occurrence of such genetically modified cells may lead to lens opacification. For a quantitative risk estimation for astronauts and space travelers it is necessary to know the relative biological effectiveness (RBE), because the spacial and temporal distribution of initial physical damage induced by cosmic radiation differ significantly from that of X-rays. RBEs for the induction of DNA strand breaks and the efficiency of repair of these breaks were measured in cultured diploid bovine lens epithelial cells exposed to different LET irradiation to either 300 kV X-rays or to heavy ions at the UNILAC accelerator at GSI. Accelerated ions from Z=8 (O) to Z=92 (U) were used. Strand breaks were measured by hydroxyapatite chromatography of alkaline unwound DNA (overall strand breaks). Results showed that DNA damage occurs as a function of dose, of kinetic energy and of LET. For particles having the same LET the severity of the DNA damage increases with dose. For a given particle dose, as the LET rises, the numbers of DNA strand breaks increase to a maximum and then reach a plateau or decrease. Repair kinetics depend on the fluence (irradiation dose). At any LET value, repair is much slower after heavy ion exposure than after X-irradiation. For ions with an LET of less than 10,000 keV micrometers-1 more than 90 percent of the strand breaks induced are repaired within 24 hours. At higher particle fluences, especially for low energetic particles with a very high local density of energy deposition within the particle track, a higher proportion of non-rejoined breaks is found, even after prolonged periods of incubation. At the highest LET value (16,300 keV micrometers-1) no significant repair is observed. These LET-dependencies are consistent with the current mechanistic model for radiation induced cataractogenesis which postulates that genomic damage to the surviving fraction of epithelial cells is responsible for lens opacification. c2003 COSPAR.

AN - 73657992; 12971404 AB - Large uncertainties are associated with estimates of equivalent dose and cancer risk for crews of long-term space missions. Biological dosimetry in astronauts is emerging as a useful technique to compare predictions based on quality factors and risk coefficients with actual measurements of biological damage in-flight. In the present study, chromosomal aberrations were analyzed in one Italian and eight Russian cosmonauts following missions of different duration on the MIR and the international space station (ISS). We used the technique of fluorescence in situ hybridization (FISH) to visualize translocations in chromosomes 1 and 2. In some cases, an increase in chromosome damage was observed after flight, but no correlation could be found between chromosome damage and flight history, in terms of number of flights at the time of sampling, duration in space and extra-vehicular activity. Blood samples from one of the cosmonauts were exposed in vitro to 6 MeV X-rays both before and after the flight. An enhancement in radiosensitivity induced by the spaceflight was observed. c2003 COSPAR. Published by Elsevier Science Ltd. All rights reserved.

AN - 73657843; 12971410 AB - The question of the appropriate extrapolation to low dose has long been a subject of controversy. A linear no-threshold model is favored by regulatory bodies as the basis of RBE assignments and estimates of radiation hazards to the general population. This model is largely supported by extensive application of the linear-quadratic survival formula "fitted" statistically to a wide variety of experimental data obtained at doses typically exceeding 1 Gy, and then extrapolated to mGy for practical applications, and even to the prediction of hazards from single electrons. Such extrapolations are questionable at best, and may even prove hazardous for risk evaluations. Fluence and geometry rather than dose based data are proposed as a basis for a limiting "threshold" for a "low dose" extrapolation. The proposed threshold is one where the fluence of particles is one per square micron, where on average only 2/3 of the 1 micrometers2 pixels covering an irradiated area are traversed by one or more particles. The corresponding dose threshold is determined by the LET of the bombarding radiation. For relativistic electrons this dose is about 0.032 Gy. c2003 COSPAR. Published by Elsevier Science Ltd.

AN - 73653803; 14503512 AB - In addition to green microalgae, aquatic higher plants are likely to play an important role in aquatic food production modules in bioregenerative systems for producing feed for fish, converting CO2 to O2 and remedying water quality. In the present study, the effects of culture conditions on the net photosynthetic rate of a rootless submerged plant, Ceratophyllum demersum L., was investigated to determine the optimum culture conditions for maximal function of plants in food production modules including both aquatic plant culture and fish culture systems. The net photosynthetic rate in plants was determined by the increase in dissolved O2 concentrations in a closed vessel containing a plantlet and water. The water in the vessel was aerated sufficiently with a gas containing a known concentration of CO2 gas mixed with N2 gas before closing the vessel. The CO2 concentrations in the aerating gas ranged from 0.3 to 10 mmol mol-1. Photosynthetic photon flux density (PPFD) in the vessel ranged from 0 (dark) to 1.0 mmol m-2 s-1, which was controlled with a metal halide lamp. Temperature was kept at 28 degrees C. The net photosynthetic rate increased with increasing PPFD levels and was saturated at 0.2 and 0.5 mmol m-2 s-1 PPFD under CO2 levels of 1.0 and 3.0 mmol mol-1, respectively. The net photosynthetic rate increased with increasing CO2 levels from 0.3 to 3.0 mmol mol-1 showing the maximum value, 75 nmol O2 gDW-1 s-1, at 2-3 mmol mol-1 CO2 and gradually decreased with increasing CO2 levels from 3.0 to 10 mmol mol-1. The results demonstrate that C. demersum could be an efficient CO2 to O2 converter under a 2.0 mmol mol-1 CO2 level and relatively low PPFD levels in aquatic food production modules. c2003 COSPAR.

AN - 73641250; 12971406 AB - In the 21st century, an increasing number of astronauts will visit the International Space Station (ISS) for prolonged times. Therefore it is of utmost importance to provide necessary basic knowledge concerning risks to their health and their ability to work on the station and during extravehicular activities (EVA) in free space. It is the aim of one experiment of the German project TRIPLE-LUX (to be flown on the ISS) to provide an estimation of health risk resulting from exposure of the astronauts to the radiation in space inside the station as well as during extravehicular activities on one hand, and of exposure of astronauts to unavoidable or as yet unknown ISS-environmental genotoxic substances on the other. The project will (i) provide increased knowledge of the biological action of space radiation and enzymatic repair of DNA damage, (ii) uncover cellular mechanisms of synergistic interaction of microgravity and space radiation and (iii) examine the space craft milieu with highly specific biosensors. For these investigations, the bacterial biosensor SOS-LUX-LAC-FLUORO-Toxicity-test will be used, combining the SOS-LUX-Test invented at DLR Germany (Patent) with the commercially available LAC-FLUORO-Test. The SOS-LUX-Test comprises genetically modified bacteria transformed with the pBR322-derived plasmid pPLS-1. This plasmid carries the promoterless lux operon of Photobacterium leiognathi as a reporter element under control of the DNA-damage dependent SOS promoter of ColD as sensor element. This system reacts to radiation and other agents that induce DNA damages with a dose dependent measurable emission of bioluminescence of the transformed bacteria. The analogous LAC-FLUORO-Test has been developed for the detection of cellular responses to cytotoxins. It is based on the constitutive expression of green fluorescent protein (GFP) mediated by the bacterial protein expression vector pGFPuv (Clontech, Palo Alto, USA). In response to cytotoxic agents, this system reacts with a dose-dependent reduction of GFP-fluorescence. Currently, a fully automated miniaturized hardware system for the bacterial set up, which includes measurements of luminescence and fluorescence or absorption and the image analysis based evaluation is under development. During the first mission of the SOS-LUX-LAC-FLUORO-Toxicity-Test on the ISS, a standardized, DNA-damaging radiation source still to be determined will be used as a genotoxic inducer. A panel of recombinant Salmonella typhimurium strains carrying either the SOS-LUX plasmid or the fluorescence-mediating lac-GFPuv plasmid will be used to determine in parallel on one microplate the genotoxic and the cytotoxic action of the applied radiation in combination with microgravity. Either in addition to or in place of the fluorometric measurements of the cytotoxic agents, photometric measurements will simultaneously monitor cell growth, giving additional data on survival of the cells. The obtained data will be available on line during the TRIPLE-LUX mission time. Though it is the main goal during the TRIPLE-LUX mission to measure the radiation effect in microgravity, the SOS-LUX-LAC-FLUORO-Toxicity-test in principle is also applicable as a biomonitor for the detection and measurement of genotoxic substances in air or in the (recycled) water system on the ISS or on earth in general. c2003 COSPAR.

AN - 73641185; 12971403 AB - The multiparametric dosimetry system that we are developing for medical radiological defense applications could be adapted for spaceflight environments. The system complements the internationally accepted personnel dosimeters and cytogenetic analysis of chromosome aberrations, considered the best means of documenting radiation doses for health records. Our system consists of a portable hematology analyzer, molecular biodosimetry using nucleic acid and antigen-based diagnostic equipment, and a dose assessment management software application. A dry-capillary tube reagent-based centrifuge blood cell counter (QBC Autoread Plus, Becton [correction of Beckon] Dickinson Bioscience) measures peripheral blood lymphocytes and monocytes, which could determine radiation dose based on the kinetics of blood cell depletion. Molecular biomarkers for ionizing radiation exposure (gene expression changes, blood proteins) can be measured in real time using such diagnostic detection technologies as miniaturized nucleic acid sequences and antigen-based biosensors, but they require validation of dose-dependent targets and development of optimized protocols and analysis systems. The Biodosimetry Assessment Tool, a software application, calculates radiation dose based on a patient's physical signs and symptoms and blood cell count analysis. It also annotates location of personnel dosimeters, displays a summary of a patient's dosimetric information to healthcare professionals, and archives the data for further use. These radiation assessment diagnostic technologies can have dual-use applications supporting general medical-related care. Published by Elsevier Science Ltd on behalf of COSPAR.

AN - 73634927; 12971413 AB - Interaction between cell and extracellular matrix (ECM) plays a crucial role in tumor invasiveness and metastasis. Using an immortalized human bronchial epithelial (BEP2D) cell model, we showed previously that expression of a list of genes including Betaig-h3 (induced by transforming growth factor-beta), DCC (deleted in colorectal cancer), p21(cipl), c-fos, Heat shock protein (HSP27) and cytokeratin 14 were differentially expressed in several independently generated, radiation-induced tumor cell lines (TL1-TL5) relative to parental BEP2D cells. Our previous data further demonstrated that loss of tumor suppressor gene(s) as a likely mechanism of radiation carcinogenesis. In the present study, we chose Betaig-h3 and DCC that were downregulated in tumorigenic cells for further study. Restored expression of Betaig-h3 gene, not DCC gene, by transfecting cDNA into tumor cells resulted in a significant reduction in tumor growth. While integrin receptor alpha 5 beta 1 was overexpressed in tumor cells, its expression was corrected to the level found in control BEP2D cells after Betaig-h3 transfection. These data suggest that Betaig-h3 gene is involved in tumor progression by regulating integrin alpha 5 beta 1 receptor. Furthermore, exogenous TGF- beta 1 induced expression of Betaig-h3 gene and inhibited the growth of both control and tumorigenic BEP2D cells. Therefore, downregulation of Betaig-h3 gene may results from the decreased expression of upstream mediators such as TGF-beta. The findings provide strong evidence that the Betaig-h3 gene has tumor suppressor function in radiation-induced tumorigenic human bronchial epithelial cells and suggest a potential target for interventional therapy. c2003 COSPAR.

AN - 73633462; 12971407 AB - Heavy ions are more efficient in producing complex-type chromosome exchanges than sparsely ionizing radiation, and this can potentially be used as a biomarker of radiation quality. We measured the induction of complex-type chromosomal aberrations in human peripheral blood lymphocytes exposed in vitro to accelerated H-, He-, C-, Ar-, Fe- and Au-ions in the LET range of approximately 0.4-1400 keV/micrometers. Chromosomes were analyzed either at the first post-irradiation mitosis, or in interphase, following premature condensation by phosphatase inhibitors. Selected chromosomes were then visualized after FISH-painting. The dose-response curve for the induction of complex-type exchanges by heavy ions was linear in the dose-range 0.2-1.5 Gy, while gamma-rays did not produce a significant increase in the yield of complex rearrangements in this dose range. The yield of complex aberrations after 1 Gy of heavy ions increased up to an LET around 100 keV/micrometers, and then declined at higher LET values. When mitotic cells were analyzed, the frequency of complex rearrangements after 1 Gy was about 10 times higher for Ar- or Fe- ions (the most effective ions, with LET around 100 keV/micrometers) than for 250 MeV protons, and values were about 35 times higher in prematurely condensed chromosomes. These results suggest that complex rearrangements may be detected in astronauts' blood lymphocytes after long-term space flight, because crews are exposed to HZE particles from galactic cosmic radiation. However, in a cytogenetic study of ten astronauts after long-term missions on the Mir or International Space Station, we found a very low frequency of complex rearrangements, and a significant post-flight increase was detected in only one out of the ten crewmembers. It appears that the use of complex-type exchanges as biomarker of radiation quality in vivo after low-dose chronic exposure in mixed radiation fields is hampered by statistical uncertainties. c2003 COSPAR.

AN - 73633428; 12971405 AB - This presentation evaluates differences between radiation biomarkers of dose and risk and demonstrates the consequential problems associated with using biomarkers to do risk calculations following radiation exposures to the complex radiation environment found in deep space. Dose is a physical quantity, while risk is a biological quantity. Dose does not predict risk. This manuscript discusses species sensitivity factors, tissue weighting factors, and radiation quality factors derived from relative biological effectiveness (RBE). These factors are used to modify dose to make it a better predictor of risk. At low doses, where it is not possible to measure changes in risk, biomarkers have been used incorrectly as an intermediate step in predicting risk. Examples of biomarkers that do not predict risk are reviewed. Species sensitivity factors were evaluated using the Syrian hamster and the Wistar rat. Although the frequency of chromosome damage is very similar in these two species, the Wistar rat is very sensitive to radiation-induced lung cancer while the Syrian hamster is very resistant. To illustrate problems involved in using tissue weighting factors, rat trachea and deep lung tissues were compared. The similar level of chromosome damage observed in these two tissues would predict that the risk for cancer induction would be the same. However, even though large numbers of deep lung tumors result from inhaled radon, under the same exposure conditions there has never been a tracheal tumor observed. Finally, the Relative Biological Effectiveness (RBE) used to generate "quality factors" that convert exposure and dose from different types of radiation to a single measure of risk, is discussed. Important risk comparisons are done at very low doses, where the response to the reference radiation has been shown to either increase or decrease as a function of dose. Thus, the RBE and the subsequent risk predicted is more dependent on the background response of the endpoint and the shape of the dose response to the reference radiation than it is on the radiation type of interest. A large study using micronuclei as biomarkers following exposure to different energies of mono-energetic neutrons, x-rays and gamma rays delivered at very low doses (0.0 to 0.10 Gy) is reported. As additional biomarkers of risk involved in critical steps in the carcinogenic process are developed, it may become possible to base risk estimates on biological change rather than the radiation energy deposition or dose. c2003 COSPAR.

AN - 73632320; 12971408 AB - Confluent human fibroblast cells were exposed to 6 Gy gamma-rays or 200 MeV/nucleon Fe ions at 0.7 or 3 Gy. The cells were allowed to repair for 24 hours after exposure and chromosomes were collected using a premature chromosome condensation technique with calyculin-A. Chromosome aberrations were analyzed using the multicolor FISH (mFISH) technique that allows identification of both complex and truly incomplete exchanges. Results showed that both doses of the Fe ions produced higher ratios of complex to simple exchanges and lower ratio of complete to incomplete exchanges than the 6 Gy gamma-exposure. The ratios of aberration yields were similar for the two doses of Fe ions. After 0.7 Gy of Fe ions, most complex aberrations were found to involve three or four chromosomes, indicating this is the maximum number of chromosome domains traversed by a single Fe ion track.

AN - 73555604; 12971412 AB - To assess the radioadaptive response of the whole body system in mice, we examined the temporal effect of low dose priming as an indicator of challenging irradiation-induced apoptosis through a p53 tumor suppressor protein- mediated signal transduction pathway. The p53 protein also plays an important role both in cell cycle control and DNA repair through cellular signal transduction. Using severe combined immunodeficiency mice defective in DNA-dependent protein kinase catalytic subunit, we examined the role of DNA-dependent protein kinase activity in radioadaptation induced by low dose irradiation. Specific pathogen free 5-week-old female severe combined immunodeficiency mice and the parental mice (CB- 17 Icr +/+) were irradiated with X-ray at 3.0 Gy at 1, 2, 3 or 4 weeks after the conditioning irradiation at 0.15, 0.30, 0.45 or 0.60 Gy. The mice spleens were fixed for immunohistochemistry 12 h after the challenging irradiation. The p53-dependent apoptosis related Bax proteins on formalin-fixed paraffin-embedded sections were stained by the avidin-biotin peroxidase complex method. The apoptosis incidence in the sections was measured by hematoxylin-eosin staining. The frequency of Bax- and apoptosis-positive cells increased up to 12 h after the challenging irradiation in the spleen of both mice. However, these cells were not observed after a low dose irradiation at 0.15-0.60 Gy. When pre-irradiation at 0.45 Gy 2 weeks before the challenging irradiation at 3.0 Gy was performed, Bax accumulation and apoptosis induced by challenging irradiation were depressed in the spleens of CB-17 Icr +/+ mice, but not in severe combined immunodeficiency mice. These data suggest that DNA-dependent protein kinase might play a major role in radioadaptation induced by pre-irradiation with a low dose in mice spleen.

AN - 73555554; 12971411 AB - The space radiation environment is a mixed field consisting of different particles having different energies, including high charge and energy (HZE) ions. Conventional measurements of absorbed doses may not be sufficient to completely characterise the radiation field and perform reliable estimates of health risks. Biological dosimetry, based on the observation of specific radiation-induced endpoints (typically chromosome aberrations), can be a helpful approach in case of monitored exposure to space radiation or other mixed fields, as well as in case of accidental exposure. Furthermore, various ratios of aberrations (e.g. dicentric chromosomes to centric rings and complex exchanges to simple exchanges) have been suggested as possible fingerprints of radiation quality, although all of them have been subjected to some criticisms. In this context a mechanistic model and a Monte Carlo code for the simulation of chromosome aberration induction were developed. The model, able to provide dose-responses for different aberrations (e.g. dicentrics, rings, fragments, translocations, insertions and other complex exchanges), was further developed to assess the dependence of various ratios of aberrations on radiation quality. The predictions of the model were compared with available data, whose experimental conditions were faithfully reproduced. Particular attention was devoted to the scoring criteria adopted in different laboratories and to possible biases introduced by interphase death and mitotic delay. This latter aspect was investigated by taking into account both metaphase data and data obtained with Premature Chromosome Condensation (PCC). c2003 COSPAR. Published by Elsevier Science Ltd.

AN - 73555494; 12971409 AB - Long-term manned exploratory missions are planned for the future. Exposure to high-energy neutrons, protons and high charge and energy particles during a deep space mission, needs protection against the detrimental effects of space radiation. It has been suggested that exposure to unpredictable extremely large solar particle events would kill the astronauts without massive shielding. To reduce this risk to astronauts and to minimize the need for shielding, astronauts with highest significant adaptive responses should be chosen. It has been demonstrated that some humans living in very high natural radiation areas have acquired high adaptive responses to external radiation. Therefore, we suggest that for a deep space mission the adaptive response of all potential crew members be measured and only those with high adaptive response be chosen. We also proclaim that chronic exposure to elevated levels of radiation can considerably decrease radiation susceptibility and better protect astronauts against the unpredictable exposure to sudden and dramatic increase in flux due to solar flares and coronal mass ejections. c2003 COSPAR.

AN - 73027864; 12580190 AB - The degradation of an anionic surfactant (Igepon TC-42) was investigated as part of an integrated study of direct recycling of human hygiene water through hydroponic plant growth systems. Several chemical approaches were developed to characterize the degradation of Igepon and to measure the accumulation of intermediates such as fatty acids and methyl taurine. Igepon was rapidly degraded as indicated by the reduction of methylene blue active substances (MBAS) and component fatty acids. The Igepon degradation rate continued to increase over a period of several weeks following repeated daily exposure to 18 micrograms/l Igepon. The accumulation of free fatty acids and methyl taurine was also observed during decomposition of Igepon. The concentration of methyl taurine was below detection limit (0.2 nmol/ml) during the slow phase of Igepon degradation, and increased to 1-2 nmol/ml during the phase of rapid degradation. These findings support a degradation pathway involving initial hydrolysis of amide to release fatty acids and methyl taurine, and subsequent degradation of these intermediates.

SILEYE-2 was placed on MIR in 1997 and has been working since then. It consists of an array of 6 active silicon strip detectors which allow nuclear and energetic identification of cosmic rays in the energy range between approximately 30 and 200 MeV/n. The device is attached to an helmet and connected to an eye mask which shields the cosmonaut eyes from light and allow studies of the Light Flashes (LF) phenomenon. In addition to the study of the causes of LF, the device is used to perform real time long term radiation environment monitoring inside the MIR, performing measurements in solar quiet and active days. c2002 COSPAR.

AN - 73022289; 12577903 AB - Radiation protection is essential to enable humans to live and work safely in space. Predictions about the nature and magnitude of the risks posed by space radiation are subject to very large uncertainties. Prudent use of worst-case scenarios may impose unacceptable constraints on shielding mass for spacecraft or habitats, tours of duty of crews on Space Station, and on the radius and duration of sorties on planetary surfaces. The NASA Space Radiation Health Program has been devised to develop the knowledge required to accurately predict and to efficiently manage radiation risk. The knowledge will be acquired by means of a peer-reviewed, largely ground-based and investigator-initiated, basic science research program. The NASA Strategic Plan to accomplish these objectives in a manner consistent with the high priority assigned to the protection and health maintenance of crews will be presented.

AN - 73021198; 12577896 AB - For systematic human Mars exploration, meeting crew safety requirements, it seems perspective to assemble into a spacecraft: an electrical rocket, a well-shielded long-term life support system, and a manipulator-robots operating in combined "presence effect" and "master-slave" mode. The electrical spacecraft would carry humans to the orbit of Mars, providing short distance (and low signal time delay) between operator and robot-manipulators, which are landed on the surface of the planet. Long-term hybrid biological and physical/chemical LSS could provide environment supporting human health and well being. Robot-manipulators operating in "presence effect" and "master-slave" mode exclude necessity of human landing on Martian surface decreasing the level of risk for crew. Since crewmen would not have direct contact with the Martian environment then the problem of mutual biological protection is essentially reduced. Lightweight robot-manipulators, without heavy life support systems and without the necessity of returning to the mother vessel, could be sent as scouts to different places on the planet surface, scanning the most interesting for exobiological research site. Some approximate estimations of electric spacecraft, long-term hybrid LSS, radiation protection and mission parameters are conducted and discussed. c2002 COSPAR. Published by Elsevier Science Ltd.

AN - 73016547; 12577948 AB - Human missions to Mars are planned to happen within this century. Activities associated therewith will interact with the environment of Mars in two reciprocal ways: (i) the mission needs to be protected from the natural environmental elements that can be harmful to human health, the equipment or to their operations; (ii) the specific natural environment of Mars should be protected so that it retains its value for scientific and other purposes. The following environmental elements need to be considered in order to protect humans and the equipment on the planetary surface: (i) cosmic ionizing radiation, (ii) solar particle events; (iii) solar ultraviolet radiation; (iv) reduced gravity; (v) thin atmosphere; (vi) extremes in temperatures and their fluctuations; and (vii) surface dust. In order to protect the planetary environment, the requirements for planetary protection as adopted by COSPAR for lander missions need to be revised in view of human presence on the planet. Landers carrying equipment for exobiological investigations require special consideration to reduce contamination by terrestrial microorganisms and organic matter to the greatest feasible extent. Records of human activities on the planet's surface should be maintained in sufficient detail that future scientific experimenters can determine whether environmental modifications have resulted from explorations. c2002 COSPAR.

AN - 73014169; 12577926 AB - Life support approaches for Mars missions are evaluated using an equivalent system mass (ESM) approach, in which all significant costs are converted into mass units. The best approach, as defined by the lowest mission ESM, depends on several mission parameters, notably duration, environment and consequent infrastructure costs, and crew size, as well as the characteristics of the technologies which are available. Generally, for the missions under consideration, physicochemical regeneration is most cost effective. However, bioregeneration is likely to be of use for producing salad crops for any mission, for producing staple crops for medium duration missions, and for most food, air and water regeneration for long missions (durations of a decade). Potential applications of in situ resource utilization need to be considered further. c2002 Published by Elsevier Science Ltd on behalf of COSPAR.

A probe on the influence of cosmic radiation and microgravity on the central nervous system during long flights. AN - 73011576; 12577991 AB - The ALTEA project participates to the quest for increasing the safety of manned space flights. It addresses the problems related to possible functional damage to neural cells and circuits due to particle radiation in space environment. Specifically it aims at studying the functionality of the astronauts' Central Nervous Systems (CNS) during long space flights and relating it to the peculiar environments in space, with a particular focus on the particle flux impinging in the head. The project is a large international and multidisciplinary collaboration. Competences in particle physics, neurophysiology, psychophysiology, electronics, space environment, data analyses will work together to construct the fully integrated vision electrophysiology and particle analyser system which is the core device of the project: an helmet-shaped multi-sensor device that will measure concurrently the dynamics of the functional status of the visual system and passage of each particle through the brain within a pre-determined energy window. ALTEA is scheduled to fly in the International Space Station in late 2002. One part of the multi-sensor device, one of the advanced silicon telescopes, will be launched in the ISS in early 2002 and serve as test for the final device and as discriminating dosimeter for the particle fluences within the ISS. c2002 COSPAR.

AN - 73011509; 12577965 AB - The search for traces of extinct and extant life on Mars will be extended to beneath the surface of the planet. Current data from Mars missions suggesting the presence of liquid water early in Mars' history and mathematical modeling of the fate of water on Mars imply that liquid water may exist deep beneath the surface of Mars. This leads to the hypothesis that life may exist deep beneath the Martian surface. One possible scenario to look for life on Mars involves a series of unmanned missions culminating with a manned mission drilling deep into the Martian subsurface (approximately 3Km), collecting samples, and conducting preliminary analyses to select samples for return to earth. This mission must address both forward and back contamination issues, and falls under planetary protection category V. Planetary protection issues to be addressed include provisions stating that the inevitable deposition of earth microbes by humans should be minimized and localized, and that earth microbes and organic material must not contaminate the Martian subsurface. This requires that the drilling equipment be sterilized prior to use. Further, the collection, containment and retrieval of the sample must be conducted such that the crew is protected and that any materials returning to earth are contained (i.e., physically and biologically isolated) and the chain of connection with Mars is broken. c2002 COSPAR.

AN - 73010036; 12580179 AB - We carried out three experiments with Super Dwarf wheat in the Bulgarian/Russian growth chamber Svet (0.1 m2 growing area) on the Space Station Mir. This paper mostly describes the first of these NASA-supported trials, began on Aug. 13, 1995. Plants were sampled five times and harvested on Nov. 9 after 90 days. Equipment failures led to low irradiance (3, then 4 of 6 lamp sets failed), instances of high temperatures (ca. 37 degrees C), and sometimes excessive substrate moisture. Although plants grew for the 90 d, no wheat heads were produced. Considering the low light levels, plants were surprisingly green, but of course biomass production was low. Plants were highly disoriented (low light, mirror walls?). Fixed and dried samples and the root module were returned on the U.S. Shuttle Atlantis on Nov. 20, 1995. Samples of the substrate, a nutrient-charged zeolite called Balkanine, were taken from the root module, carefully examined for roots, weighed, dried, and reweighed. The Svet control unit and the light bank were shipped to Moscow. An experiment validation test (EVT) of plant growth and experimental procedures, carried out in Moscow, was highly successful. Equipment built in Utah to measure CO2, H2O vapor, irradiance, air and leaf (IR) temperature, O2, pressure, and substrate moisture worked well in the EVT and in space. After this manuscript was first prepared, plants were grown in Mir with a new light bank and controller for 123 d in late 1996 and 39 days in 1996/1997. Plants grew exceptionally well with higher biomass production than in any previous space experiment, but the ca. 280 wheat heads that were produced in 1996 contained no seeds. Ethylene in the cabin atmosphere was responsible. c2002 Published by Elsevier Science Ltd on behalf of COSPAR.

The errors are shown to be inherent to most of the measurements made to be the monitoring of the high-energy radiation in the space. The level of the systematic errors of the measurements varies with energy, thus resulting in distortions of the solar energetic particle spectra based on the measurement data. The erroneous experimental data have resulted in spurious estimates of space radiation environment and give rise to erroneous physical conclusions. c2003 COSPAR. Published by Elsevier Ltd.

AN - 71557674; 15015476 AB - In Zea mays L., changes in orientation of stems are perceived by the pulvinal tissue, which responds to the stimulus by differential growth resulting in upward bending of the stem. Gravity is perceived in the bundle sheath cells, which contain amyloplasts that sediment to the new cell base when a change in the gravity vector occurs. The mechanism by which the mechanical signal is transduced into a physiological response is so far unknown for any gravity perceiving tissue. It is hypothesized that this involves interactions of amyloplasts with the plasma membrane and/or ER via cytoskeletal elements. To gain further insights into this process we monitored amyloplast movements in response to gravistimulation. In a pharmacological approach we investigated how the dynamics of plastid sedimentation are affected by actin and microtubule (MT) disrupting drugs. Dark grown caulonemal filaments of the moss Physcomitrella patens respond to gravity vector changes with a reorientation of tip growth away from the gravity vector. MT distributions in tip cells were monitored over time and MTs were seen to accumulate preferentially on the lower flank of the tip 30 min after a 90 degree turn. Using a self-referencing Ca2+ selective ion probe, we found that growing caulonemal filaments exhibit a Ca2+ influx at the apical dome, similar to that reported previously for other tip growing cells. However, in gravistimulated Physcomitrella filaments the region of Ca2+ influx is not confined to the apex, but extends about 60 micrometers along the upper side of the filament. Our results indicate an asymmetry in the Ca2+ flux pattern between the upper and side of the filament suggesting differential activation of Ca2+ permeable channels at the plasma membrane. c2003 COSPAR.

AN - 71554996; 14989303 AB - To select suitable light source for higher plant cultivation in the controlled ecological life support system of the future space station. The experiment was carried out in the Space Higher Plant Cultivation Ground-based Experimental Facility (SHPCGEF); four combinations of two red and blue light-emitting diode (LED) were utilized as light sources; soilless cultivation technique with porous ceramic tubes and porous ceramic particles was utilized in the growth system. The plants grown under the shelf of pure red LED showed a lying-down state in early stage, and stood erect in later period with slender and long stems; the plants under various combinations of red and blue LED grew with nearly normal state, but the plants under the combination of 90% red and 10% blue LED possessed the best comprehensive indexes. The normal growth and development of plantlets needs two light sources of red and blue LED, and the combination of 90% red and 10% blue LED is the optimum one among those tested combinations.

Preliminary results. AN - 71552448; 14997884 AB - The "SCORPION" program onboard the Russian Segment (RS) of the International Space Station (ISS) is designed to carry out complex research of the effects of the nar-Earth space parameters on the conditions under which various experiments and operations are being conducted. Special attention in this program was paid to the biological objects onboard the orbital station, e.g. it was found that variation in the number of colony forming units (micromicets and bacteria) correlates with the solar activity and the absorbed dose. The "SCORPION" experiment onboard the RS ISS started in January 2002. It was designed to measure the following parameters inside the space absorbed doses in different places inside the RS ISS, the fluxes of energetic charged particles, neutrons and gamma-quanta; the vectors of the magnetic field and low-frequency electromagnetic waves. At the same time the growth of micromicets on the samples of various materials was studied. The description of the "SCORPION" experiment and the preliminary results obtained onboard the RS ISS in 2002 are presented. c2003 COSPAR. Published by Elsevier Ltd. All rights reserved.

AN - 71542230; 14727670 AB - The distribution of the solar cosmic radiation flux over the earth is not uniform, but the result of complex phenomena involving the interplanetary magnetic field, the geomagnetic field and latitude and longitude of locations on the earth. The latitude effect relates to the geomagnetic shield; the longitude effect relates to local time. For anisotropic solar cosmic ray events the maximum particle flux is always along the interplanetary magnetic field direction, sometimes called the Archimedean spiral path from the sun to the earth. During anisotropic solar cosmic ray event, the locations on the earth viewing "sunward" into the interplanetary magnetic field direction will observe the largest flux (when adjustments are made for the magnetic latitude effect). To relate this phenomena to aircraft routes, for anisotropic solar cosmic ray events that occur during "normal quiescent" conditions, the maximum solar cosmic ray flux (and corresponding solar particle radiation dose) will be observed in the dawn quadrant, ideally at about 06 hours local time.

AN - 71515344; 14686436 AB - Despite extensive studies on plant gravitropism this phenomenon is still poorly understood. The separation of gravity sensing, signal transduction and response is a common concept but especially the mechanism of gravisensing remains unclear. This paper focuses on microinjection as powerful tool to investigate gravisensing in plants. We describe the microinjection of magnetic beads in rhizoids of the green alga Chara and related subsequent manipulation of the gravisensing system. After injection, an external magnet can control the movement of the magnetic beads. We demonstrate successful injection of magnetic beads into rhizoids and describe a multitude of experiments that can be carried out to investigate gravitropism in Chara rhizoids. In addition to examining mechanical properties, bead microinjection is also useful for probing the function of the cytoskeleton by coating beads with drugs that interfere with the cytoskeleton.

AN - 71512025; 14727668 AB - Vertical cutoff rigidities derived from the International Geomagnetic Reference Fields (IGRF) are normally used to compute the radiation dose at a specific location and to organize the radiation dose measurements acquired at aircraft altitudes. This paper presents some of the usually ignored limits on the accuracy of the vertical cutoff rigidity models and describes some of the computational artifacts present in these models. It is noted that recent aircraft surveys of the radiation dose experienced along specific flight paths is sufficiently precise that the secular variation of the geomagnetic field is observable.

AN - 71511991; 14727661 AB - The risks to aircrew health posed by prolonged exposure to low levels of ionizing radiation at aircraft altitudes have recently received renewed attention. Civil and military aircraft currently on the drawing board are expected to operate at higher altitudes (>12 km) and fly longer ranges than do existing aircraft, thereby exposing their crews to higher levels of ionizing radiation, for longer periods of time. We are currently carrying out dosimetric measurements of the ionizing radiation environment at approximately 20 km altitude using portable Si detectors aboard NASA's two ER-2 high altitude research aircraft. The instruments, Liulin-4J, have been extensively calibrated at several particle accelerators. With these instruments, we can measure not only absorbed dose, but also variation of the absorbed dose as a function of time. We report radiation dose measurements as function of time, altitude, and latitude for several ER-2 missions. c2003 COSPAR. Published by Elsevier Ltd. All rights reserved.

AN - 71511406; 14727660 AB - Crews of future high-altitude commercial aircraft may be significantly exposed to atmospheric cosmic radiation from galactic cosmic rays (GCR). To help determine such exposures, the Atmospheric Ionizing Radiation Project, an international collaboration of 15 laboratories, made simultaneous radiation measurements with 14 instruments on a NASA ER-2 high-altitude aircraft. The primary instrument was a sensitive extended-energy multisphere neutron spectrometer, which was also used to make measurements on the ground. Its detector responses were calculated for neutrons and charged hadrons at energies up to 100 GeV using the radiation transport code MCNPX. We have now recalculated the detector responses including the effects of the airplane structure. We are also using new FLUKA calculations of GCR-induced hadron spectra in the atmosphere to correct for spectrometer counts produced by charged hadrons. Neutron spectra are unfolded from the corrected measured count rates using the MAXED code. Results for the measured cosmic-ray neutron spectrum (thermal to >10 GeV), total neutron fluence rate, and neutron dose equivalent and effective dose rates, and their dependence on altitude and geomagnetic cutoff generally agree well with results from recent calculations of GCR-induced neutron spectra. c2003 COSPAR.

AN - 71511344; 14727658 AB - A new Atmospheric Ionizing Radiation (AIR) model is currently being developed for use in radiation dose evaluation in epidemiological studies targeted to atmospheric flight personnel such as civilian airlines crewmembers. The model will allow computing values for biologically relevant parameters, e.g. dose equivalent and effective dose, for individual flights from 1945. Each flight is described by its actual three dimensional flight profile, i.e. geographic coordinates and altitudes varying with time. Solar modulated primary particles are filtered with a new analytical fully angular dependent geomagnetic cut off rigidity model, as a function of latitude, longitude, arrival direction, altitude and time. The particle transport results have been obtained with a technique based on the three-dimensional Monte Carlo transport code FLUKA, with a special procedure to deal with HZE particles. Particle fluxes are transformed into dose-related quantities and then integrated all along the flight path to obtain the overall flight dose. Preliminary validations of the particle transport technique using data from the AIR Project ER-2 flight campaign of measurements are encouraging. Future efforts will deal with modeling of the effects of the aircraft structure as well as inclusion of solar particle events. Published by Elsevier Ltd on behalf of COSPAR.

AN - 71511199; 14727657 AB - The Supersonic Transport (SST) program, proposed in 1961, first raised concern for the exposure of pregnant occupants by solar energetic particles (SEP), and neutrons were suspected to have a main role in particle propagation deep into the atmosphere. An eight-year flight program confirmed the role of SEP as a significant hazard and of the neutrons as contributing over half of the galactic cosmic ray exposures, with the largest contribution from neutrons above 10 MeV. The FAA Advisory Committee on the Radiobiological Aspects of the SST provided operational requirements. The more recent lowering of ICRP-recommended exposure limits (1990) with the classification of aircrew as "radiation workers" renewed interest in GCR background exposures at commercial flight altitudes and stimulated epidemiological studies in Europe, Japan, Canada and the USA. The proposed development of a High Speed Civil Transport (HSCT) required validation of the role of high-energy neutrons, and this resulted in ER-2 flights at solar minimum (June 1997) and studies on effects of aircraft materials on interior exposures. Recent evaluation of health outcomes of DOE nuclear workers resulted in legislation for health compensation in year 2000 and recent European aircrew epidemiological studies of health outcomes bring renewed interest in aircraft radiation exposures. As improved radiation models become available, it is imperative that a corresponding epidemiological program of US aircrew be implemented. Published by Elsevier Ltd on behalf of COSPAR.

AN - 71510165; 14727666 AB - High-energy solar particles, produced in association with solar flares and coronal mass ejections, occasionally bombard the earth's atmosphere. resulting in radiation intensities additional to the background cosmic radiation. Access of these particles to the earth's vicinity during times of geomagnetic disturbances are not adequately described by using static geomagnetic field models. These solar fluxes are also often distributed non uniformly in space, so that fluxes measured by satellites obtained at great distances from the earth and which sample large volumes of space around the earth cannot be used to predict fluxes locally at the earth's surface. We present here a method which uses the ground-level neutron monitor counting rates as adjoint sources of the flux in the atmosphere immediately above them to obtain solar-particle effective dose rates as a function of position over the earth's surface. We have applied this approach to the large September 29-30, 1989 ground-level event (designated GLE 42) to obtain the magnitude and distribution of the solar-particle effective dose rate from an atypically large event. The results of these calculations clearly show the effect of the softer particle spectra associated with solar particle events, as compared with galactic cosmic rays, results in a greater sensitivity to the geomagnetic field, and, unlike cosmic rays, the near-absence of a "knee" near 60 degrees geomagnetic latitude. c2003 COSPAR.

AN - 71510124; 14727664 AB - The assessment of exposure to cosmic radiation on board aircraft is one of the preoccupations of organizations responsible for radiation protection. The cosmic radiation particle flux increases with altitude and latitude and depends on the solar activity. The radiation exposure has been estimated on several airlines using transatlantic, Siberian and transequatorial routes on board subsonic and supersonic aircraft, to illustrate the effect of these parameters. Measurements have been obtained with a tissue equivalent proportional counter using the microdosimetric technique. Data have been collected at maximum solar activity in 1991-92 and at minimum in 1996-98. The lowest mean dose rate measured was 3 microSv/h during a Paris-Buenos Aires flight in 1991; the highest was 6.6 microSv/h during a Paris-Tokyo flight using a Siberian route and 9.7 microSv/h on Concorde in 1996-97. The mean quality factor is around 1.8. The corresponding annual effective dose, based on 700 hours of flight for subsonic aircraft and 300 hours for Concorde, can be estimated between 2 mSv for least-exposed routes and 5 mSv for more exposed routes. c2003 COSPAR.

AN - 71509947; 14727667 AB - Solar particle events can give greatly enhanced radiation at aircraft altitudes, but are both difficult to predict and to calculate retrospectively. This enhanced radiation can give significant dose to aircrew and greatly increase the rate of single event effects in avionics. Validation of calculations is required but only very few events have been measured in flight. The CREAM detector on Concorde detected the event of 29 September 1989 and also four periods of enhancement during the events of 19-24 October 1989. Instantaneous rates were enhanced by up to a factor ten compared with quiet-time cosmic rays, while flight-averages were enhanced by up to a factor six. Calculations are described for increases in radiation at aircraft altitudes using solar particle spectra in conjunction with Monte Carlo radiation transport codes. In order to obtain solar particle spectra with sufficient accuracy over the required energy range it is necessary to combine space data with measurements from a wide range of geomagnetically dispersed, ground-level neutron monitors. Such spectra have been obtained for 29 September 1989 and 24 October 1989 and these are used to calculate enhancements that are compared with the data from CREAM on Concorde. The effect of cut-off rigidity suppression by geomagnetic activity is shown to be significant. For the largest event on record on 23 February 1956, there are no space data but there are data from a number of ground-level cosmic-ray detectors. Predictions for all events show very steep dependencies on both latitude and altitude. At high latitude and altitude (17 km) calculated increases with respect to cosmic rays are a factor 70 and 500 respectively for 29 September 1989 and 23 February 1956. The levels of radiation for high latitude, subsonic routes are calculated, using London to Los Angeles as an example, and can exceed 1 mSv, which is significantly higher than for Concorde routes from Europe to New York.

AN - 71509888; 14727665 AB - The LIULIN-3M instrument is a further development of the LIULIN dosimeter-radiometer, used on the MIR spacestation during the 1988-1994 time period. The LIULIN-3M is designed for continuous monitoring of the radiation environment during the BION-12 satellite flight in 1999. A semiconductor detector with 1 mm thickness and cm2 area is contained in the instrument. Pulse high analysis technique is used to determine the energy losses in the detector. The final data from the instrument are the flux and the dose rate for the exposure time and 256 channels of absorbed dose spectra based on the assumption that the particle flux is normal to the detector. The LIULIN-3M instrument was calibrated by proton fluxes with different energies at the Indiana University Cyclotron Facility in June 1997 and had been used for radiation measurements during commercial aircraft flights. The calibration procedure and some flight results are presented in this paper. c2003 COSPAR. Published by Elsevier Ltd. All rights reserved.

AN - 71507516; 14727669 AB - We have developed a dynamic geomagnetic vertical cutoff rigidity model that predicts the energetic charged particle transmission through the magnetosphere. Initially developed for space applications, we demonstrate the applicability of this library of cutoff rigidity models for computing aircraft radiation dose. The world grids of vertical cutoff rigidities were obtained by particle trajectory tracing in a magnetospheric model. This reference set of world grids of vertical cutoff rigidities calculated for satellite altitudes covers all magnetic activity levels from super quiet to extremely disturbed (i.e., Kp indices ranging from 0 to 9+) for every three hours in universal time. We utilize the McIlwain "L" parameter as the basis of the interpolation technique to reduce these initial satellite altitude vertical cutoff rigidities to cutoff rigidity values at aircraft altitudes.

AN - 71505372; 14727663 AB - The radiation fields onboard aircraft are complex (EURADOS, 1996), and several methods are used to characterise them for radiation protection. We have tested a spectrometer based on Si-diode at different sources and accelerator facilities. The energy deposited in the diode is analysed to estimate the contribution of different radiations to dosimetry quantities. The spectrum of energy deposition events onboard aircraft is similar to that registered in the CERN high-energy reference field. We used this similarity to determine the correction factors to appreciate radiation protection quantities from the results of onboard measurements. During 2001-2002, the spectrometer was used to acquire measurements onboard commercial aircraft during five long-term exposures. All necessary flight parameters were acquired; thus permitting calculations of the onboard effective dose and/or ambient dose equivalent by means of both the CARI 6 and the EPCARD codes and comparison with the results of the measurements. It was found that the apparent ambient dose equivalent values from measured data are in reasonable agreement with the results of calculations. Quantitative analysis of this agreement as a function of flight parameters (geomagnetic position, solar activity variations, etc.) is presented. During one flight, an important solar event (GLE 60 on 15 April 2001) was recorded by the spectrometer. In some other cases the measurements during a Forbush decreases were acquired. These extremes were well registered by the equipment and the data obtained are analyzed. c2003 COSPAR. Published by Elsevier Ltd. All rights reserved.

AN - 71483335; 14696589 AB - The European Space Agency has recently initiated a study of the human responses, limits and needs with regard to the stress environments of interplanetary and planetary missions. Emphasis has been laid on human health and performance care as well as advanced life support developments including bioregenerative life support systems and environmental monitoring. The overall study goals were as follows: (i) to define reference scenarios for a European participation in human exploration and to estimate their influence on the life sciences and life support requirements; (ii) for selected mission scenarios, to critically assess the limiting factors for human health, wellbeing, and performance and to recommend relevant countermeasures; (iii) for selected mission scenarios, to critically assess the potential of advanced life support developments and to propose a European strategy including terrestrial applications; (iv) to critically assess the feasibility of existing facilities and technologies on ground and in space as testbeds in preparation for human exploratory missions and to develop a test plan for ground and space campaigns; (v) to develop a roadmap for a future European strategy towards human exploratory missions, including preparatory activities and terrestrial applications and benefits. This paper covers the part of the HUMEX study dealing with lunar missions. A lunar base at the south pole where long-time sunlight and potential water ice deposits could be assumed was selected as the Moon reference scenario. The impact on human health, performance and well being has been investigated from the view point of the effects of microgravity (during space travel), reduced gravity (on the Moon) and abrupt gravity changes (during launch and landing), of the effects of cosmic radiation including solar particle events, of psychological issues as well as general health care. Countermeasures as well as necessary research using ground-based test beds and/or the International Space Station have been defined. Likewise advanced life support systems with a high degree of autonomy and regenerative capacity and synergy effects were considered where bioregenerative life support systems and biodiagnostic systems become essential. Finally, a European strategy leading to a potential European participation in future human exploratory missions has been recommended. c2003 COSPAR. Published by Elsevier Ltd. All rights reserved.

AN - 71482453; 14686435 AB - The cytoskeleton has been proposed to be a key player in the gravitropic response of higher plants. A major approach to determine the role of the cytoskeleton in gravitropism has been to use inhibitors to disrupt the cytoskeleton and then to observe the effect that such disruption has on organ bending. Several investigators have reported that actin or microtubule inhibitors do not prevent root gravitropism, leading to the conclusion that the cytoskeleton is not involved in this process. However, there are recent reports showing that disruption of the actin cytoskeleton with the actin inhibitor, latrunculin B, promotes the gravitropic response of both roots and shoots. In roots, curvature is sustained during prolonged periods of clinorotation despite short periods of gravistimulation. These results indicate that an early gravity-induced signal continues to persist despite withdrawal of the constant gravity stimulus. To investigate further the mechanisms underlying the promotive effect of actin disruption on root gravitropism, we treated maize roots with varying concentrations of latrunculin B in order to determine the lowest concentration of latrunculin B that has an effect on root bending. After a 10-minute gravistimulus, treated roots were axially rotated on a one rpm clinostat and curvature was measured after 15 hours. Our results show that 100 nM latrunculin B induced the strongest promotive effect on the curvature of maize roots grown on a clinostat. Moreover, continuously gravistimulated roots treated with 100 nM latrunculin B exhibited stronger curvature responses while decapped roots treated with this concentration of latrunculin B did not bend during continuous gravistimulation. The stronger promotive effect of low concentrations of latrunculin B on the curvature of both clinorotated and continuously gravistimulated roots suggests that disruption of the finer, more dynamic component of the actin cytoskeleton could be the cause of the enhanced tropic responses of roots to gravity. c2003 COSPAR.

AN - 71479652; 14696588 AB - The National Aeronautics and Space Administration (NASA) administrator has identified protection from radiation hazards as one of the two biggest problems of the agency with respect to human deep space missions. The intensity and strength of cosmic radiation in deep space makes this a 'must solve' problem for space missions. The Moon and two Earth-Moon Lagrange points near Moon are being proposed as hubs for deep space missions. The focus of this study is to identify approaches to protecting astronauts and habitats from adverse effects from space radiation both for single missions and multiple missions for career astronauts to these destinations. As the great cost of added radiation shielding is a potential limiting factor in deep space missions, reduction of mass, without compromising safety, is of paramount importance. The choice of material and selection of the crew profile play major roles in design and mission operations. Material trade studies in shield design over multi-segmented missions involving multiple work and living areas in the transport and duty phase of space mission's to two Earth-Moon co-linear Lagrange points (L1) between Earth and the Moon and (L2) on back side of the moon as seen from Earth, and to the Moon have been studied. It is found that, for single missions, current state-of-the-art knowledge of material provides adequate shielding. On the other hand, the choice of shield material is absolutely critical for career astronauts and revolutionary materials need to be developed for these missions. This study also provides a guide to the effectiveness of multifunctional materials in preparation for more detailed geometry studies in progress. c2003 COSPAR. Published by Elsevier Ltd.

AN - 71398777; 14632000 AB - It is known that space flight affects T lymphocyte function in both humans and animals, but there have been no papers dealing with the effect of microgravity conditions for a very short time (i.e., only 10 s). In the present study, the effect of very short time microgravity on the cytotoxicity and surface markers of human activated T lymphocytes, in vitro, was investigated using the drop-shaft type of microgravity experiment system. The levels of heat shock protein 60 and 70 (hsp60 and hsp70) were also quantified in cells exposed to these microgravity conditions. The results showed that not only the cytotoxicity but also the hsp60 levels were remarkably reduced under these conditions. JF - Habitation (Elmsford, N.Y.)

AN - 71394943; 14632003 AB - Current guidance for survivors aboard a disabled submarine (DISSUB) recommends the use of the "stir-and-fan" method of carbon dioxide (CO2) scrubbing in which the contents of canisters of lithium hydroxide (LiOH) are dispersed onto horizontal surfaces. This technique is objectionable because it releases large quantities of fine, caustic LiOH dust and it utilizes LiOH inefficiently. This report presents the results of laboratory studies of the CO2 scrubbing capabilities of two new products that might improve on "stir-and-fan": the Battelle Curtain (BC) and the Micropore Reactive Plastic Curtain (RPC). Experiments took place within a sealed hyperbaric chamber. CO2 was added to the chamber at a known mass flow that reproduced what might be encountered in a "worst-case" DISSUB scenario. Natural convection alone circulated gas within the chamber. The mass of BCs or RPCs necessary to limit CO2 to 3% for about 2 days was determined. The total scrubbing capacity (mass of CO2 scrubbed per unit mass of agent) of the BC was 0.756 +/- 0.012 (mean +/- SD), and the comparable value for the RPC was 0.808 +/- 0.007. Both products provided a scrubbing capacity that is close to the stoichiometric limit of the reaction (0.919). Neither product released sufficient caustic dust to prevent handling by a trained individual wearing no personal protective equipment. JF - Habitation (Elmsford, N.Y.)

Characteristics and implications of along-strike topographic variations AN - 52025700; 2003-014311 AB - Differences in the topography of central Nepal and Bhutan are characterized by map and profile patterns of elevation, slope, relief, and stream gradients. Nepal exhibits a narrow hinterland zone of extreme relief, steep slopes and channels, and deep fluvial dissection and a wide foreland zone of lower relief; active shortening on the Main Frontal thrust occurs far outboard of the steep topography. In contrast, Bhutan has two high-relief zones separated by a narrow, low-relief step in the topographic and river profiles; the southern zone has the higher relief, rising abruptly from the Main Frontal thrust to a series of 4000 m peaks, whereas the northern zone consists of low-relief, high-elevation, plateau-like terrain cut by widely spaced, steep-walled valleys. Spatial relationships between these geomorphic features, and geologic contrasts, are used to examine scenarios of tectonic and surface-process interactions. The observations favor a model of along-strike segmentation in which timing differences in the varying balance of uplift and erosion produce spatial differences of topographic and geologic patterns, although other interpretations are possible.

Data requirements are documented in an LDCM Data Specification. The specifications require delivery of data covering 250 Landsat scenes on a daily basis. The data are to be acquired in a manner that affords seasonal coverage of the global land mass. Data are required for the heritage reflective Thematic Mapper (TM) spectral bands plus two new bands, a blue band for coastal zone observations and a short wave infrared band for cirrus cloud detection. The specifications do not require thermal data, representing a departure from the TM heritage. The specification also requires data providing a 30 m ground sample distance for each of the spectral bands with the exception of the new cirrus cloud band at 120 m. An absolute uncertainty of 5 percent or less is required for radiometrically corrected LDCM data and the commercial operator is required to deliver data that can be registered to a cartographic projection with an uncertainty of 65 m or less. Procuring data from a commercial operator represents a new approach for the 30-year-old Landsat Program. The LDCM Data Specification will ensure that the procured data provides continuity of the Landsat data stream and advances the mission.

A 12-channel GPS navigation receiver was modified to perform bistatic radar measurements and mounted on the NCAR C-130 aircraft to make co-located measurements with the JPL PALS instrument. The reflected GPS signal-to-noise ratio measurements generated a ground track which was sensitive to the surface characteristics. Assuming surface roughness and vegetation cover to be constants over the duration of the study period, the temporal changes in the measured signals were suspected to be proportional to varying soil moisture content. The bistatic signal measurements were interpolated to a UTM grid to produce daily maps of relative change of surface soil moisture over the study region. The maps of the study region showed a transition from very dry surface soil moisture conditions to very wet conditions following precipitation events occurring in the middle of the study period. Additionally, the maps showed sensitivity to localized rainfall in areas where the scattered power increased relative to areas without precipitation. The scattered signal measurements were also compared with in situ soil moisture measurements at 32 field sites and found to follow the general soil moisture trend as a function of time. These positive initial results from the first controlled experiment of GPS bistatic radar for measuring soil moisture were encouraging. Additional analyses with the present data set and comparison with other remote sensing instruments (PALS) are planned as well as participation in future campaigns.

Because of its inaccessibility, remote sensing data will play an important role. In this study we examined the use of several remote sensing techniques for identifying the existing tundra- taiga ecotone. These include Landsat, MISR and RADARSAT data. High-resolution IKONOS images were used for local ground truth. It was found that on Landsat ETM+ summer images, reflectance from tundra and taiga at band 4 (NIR) is similar, but different at other bands such as red, and MIR bands. When the incidence angle is small, C-band HH-pol backscattering coefficients from both tundra and taiga are relatively high. The backscattering from tundra targets decreases faster than taiga targets when the incidence angle increases, because the tundra targets look smoother than taiga. Because of the shading effect of the vegetation, the MISR data, both multi-spectral data at nadir looking and multi-angle data at red and NIR bands, clearly show the transition zone.

The measurements were performed using the 300-m tall ETL Boulder Atmospheric Observatory (BAO) tower during summer through fall of 2002. In this experiment the first seasonal measurements of bare soil moisture from a stationary location using bistatic reflection of signal of opportunity were performed. Several receiving antennas offering various gain and polarization sensitivities were used. Theoretical modeling of bistatic surface scattering shows that the magnitude and width of the reflected waveform depend on the dielectric permittivity of the soil, vegetation cover, and soil roughness. By observing from a fixed tower over low grass the roughness of the reflecting area remains constant, hence variation in the signal are uniquely related to changes in the dielectric permittivity, and therefore, to soil moisture. To investigate polarization sensitivity of the reflected signal to soil moisture four endfire ( approximately 12 dB) antennas with complete circular and orthogonal polarization sensitivities were used. The high-gain antennas increased the receiver dynamic range and reduced surface multipath radio wave interference. Seasonal retrievals of soil-moisture content from multi-polarization GPS reflection data is presented and compared with in-situ soil moisture measurements.

Synthetic data are used to illustrate non-uniqueness in the inversion, but also demonstrate that effects of b and c can be separated when s, u and v are specified, even with added noise to simulate measurement errors. We have analyzed prominent short-horizontal-scale ( approximately 2 km) features in topography and velocity pattern in a local 64 km by 32 km area of the surface of Ice Stream E, West Antarctica. Our preferred interpretation of bed conditions beneath the most prominent features on the surface identifies a deep trough in the basal topography with low lubrication in the base of the trough.

However, modern studies conclude that the primordial Earth's atmosphere was too rich in CO, CO (sub 2) , and water to permit efficient synthesis of such reduced molecules as envisioned by the classic Miller-Urey experiment. Other proposed sources of terrestrial nitrogen reduction, like those within submarine vent systems, also seem to be inadequate sources of chemically reduced C-H-O-N compounds. Here, we demonstrate that nebular dust analogs have impressive catalytic properties for synthesizing prebiotic molecules. Using a catalyst analogous to nebular iron silicate condensate, at temperatures ranging from 500K to 900K, we catalyzed both the Fischer-Tropsch conversion of CO and H (sub 2) to methane and water, and the corresponding Haber-Bosch synthesis of ammonia from N (sub 2) and H (sub 2) . Remarkably, when CO, N (sub 2) , and H (sub 2) were allowed to react simultaneously, these syntheses also yielded nitrogen-containing organics such as methyl amine (CH (sub 3) NH (sub 2) ), acetonitrile (CH (sub 3) CN), and N-methyl methylene imine (H (sub 3) CNCH (sub 2) ). A fundamental consequence of this work for astrobiology is the potential for a natural chemical pathway to produce complex chemical building blocks of life throughout our own Solar System and beyond.

One of the major ways that the cosmos influences life is through the catastrophic environmental disruptions caused when comets and asteroids collide with a planet. We now recognize that such impacts have caused mass extinctions and played a major role in determining the evolution of life on Earth. The time-averaged impact flux as a function of projectile energy can be derived from lunar cratering statistics as well as the current population of near Earth asteroids (NEAs). Effects of impacts of various energies can be modeled, using data from historic impacts [such as the Cretaceous-Tertiary (KT) impactor 65 million years ago] and the observed 1994 bombardment of Jupiter by fragments of Comet Shoemaker-Levy 9. It is of particular interest to find from such models that the terrestrial environment is highly vulnerable to perturbation from impacts, so that even such a small event as the KT impact (by a projectile 10-15 km in diameter) can lead to a mass extinction. Similar considerations allow us to model the effects of still smaller (and much more likely) impacts, down to the size of the asteroid that exploded over Tunguska in 1908 (energy approximately 10 megatons). Combining the impact flux with estimates of environmental and ecological effects reveals that the greatest contemporary hazard is associated with impactors near 1 million megatons in energy ( approximately 2 km in diameter for an asteroid). The current impact hazard is significant relative to other natural hazards, and arguments can be developed to illuminate a variety of public policy issues. The first priority in any plan for defense against impactors is to survey the population of Earth-crossing NEAs and project their orbits forward in time. This is the purpose of the Spaceguard Survey, which has already found more than half of the NEAs >1 km in diameter. If there is an NEA on a collision course with Earth, it can be discovered and the impact predicted with decades or more of warning. It is then possible to consider how to deflect or disrupt the NEA. Unlike other natural hazards, the impact risk can be largely eliminated, given sufficient advanced knowledge to take action against the threatening projectile.

However, where they do occur they can potentially have an important influence on the local ecology. Some of the types of habitat created in the immediate post-impact environment are not specific to the impact phenomenon, such as hydrothermal systems and crater lakes that can be found, for instance, in post-volcanic environments, albeit with different thermal characteristics than those associated with impact. However, some of the habitats created are specifically linked to processes of impact processing. Two examples of how impact processing of target materials has created novel habitats that improve the opportunities for colonization are found in the Haughton impact structure in the Canadian High Arctic. Impact-shocked rocks have become a habitat for endolithic microorganisms, and large, impact-shattered blocks of rock are used as resting sites by avifauna. However, some materials produced by an impact, such as melt sheet rocks, can make craters more biologically depauperate than the area surrounding them. Although there are no recent craters with which to study immediate post-impact colonization, these data yield insights into generalized mechanisms of how impact processing can influence post-impact succession. Because impact events are one of a number of processes that can bring localized destruction to ecosystems, understanding the manner in which impact structures are recolonized is of ecological interest. Impact craters are a universal phenomenon on solid planetary surfaces, and so they are of potential biological relevance on other planetary surfaces, particularly Mars.

Data from the four TOMS satellites that have flown to date have been analysed with the latest SO (sub 2) /ash algorithms and incorporated into a TOMS volcanic emissions database that presently covers 22 years of SO (sub 2) and ash emissions. The 1978-2001 record comprises 102 eruptions from 61 volcanoes, resulting in 784 days of volcanic cloud observations. Regular eruptions of Nyamuragira (DR Congo) since 1978, accompanied by copious SO (sub 2) production, have contributed material on approximately 30% of the days on which clouds were observed. The latest SO (sub 2) retrieval results from Earth Probe (EP) TOMS document a period (1996-2001) lacking large explosive eruptions, and also dominated by SO (sub 2) emission from four eruptions of Nyamuragira. EP TOMS has detected the SO (sub 2) and ash produced during 23 eruptions from 15 volcanoes to date, with volcanic clouds observed on 158 days. The EP TOMS instrument began to degrade in 2001, but has now stabilized, although its planned successor (QuikTOMS) recently failed to achieve orbit. New SO (sub 2) algorithms are currently being developed for the Ozone Monitoring Instrument, which will continue the TOMS record of UV remote sensing of volcanic emissions from 2004 onwards.

Ignoring measurement noise and processing errors, the dynamic components include strong external field effects, whereas the static components reflect lithospheric and core field effects. Consistency is apparent in the correlation of all the anomaly fields at degree and order 13 and higher. However, the longer wavelength components are corrupted by errors in the core field reductions that do not account for the crustal thickness magnetic effects. To assess these magnetic effects, we developed an Antarctic crustal thickness model from free-air and computed terrain gravity effects. The pseudo magnetic effects evaluated from the crustal model indicate quite strong crustal anomaly contributions for degrees lower than 13 in the satellite magnetometer observations. The Antarctic gravity field from which the crustal thickness effects were inferred is limited by the general lack of terrestrial gravity observations.

As the wavelength of anomalies increases, geologic interpretation becomes less direct and the magnetic response of geology more complex. The long wavelength magnetic anomalies observed at the altitudes of near-Earth satellites represent the collective effect of many contiguous regional-scale geologic units. The variations also reflect the effect of the Curie isotherm that governs the thickness of the magnetic crust, and therefore may be used to constrain the models of regional variations of heat flow. This information in turn can be useful in deriving lithospheric strength variations and also constraining models of global seismological parameters. The challenge of the CHAMP magnetic experiment is to unravel this complex information beyond the level of Magsat and extract from it new knowledge regarding the Earth's lithosphere that could be used by geologists and geophysicists. There are a number of fronts along which improvements appear possible in the anomaly field and their interpretation from the overall mission characteristics of the CHAMP satellite. They are: improvements due to data redundancy and attitude determinations, better external field models, increased anomaly resolution during late-phase lower altitude part of the mission, new direct interpretation techniques and, taking advantage of gravity field from the CHAMP mission, improved interpretations resulting from correlations with gravity anomaly data through Poisson's relation. Magnetic anomaly data provide a unique perspective on geologic processes as evident from the well known example of magnetic stripes associated with the seafloor spreading--a process that could not be inferred readily through other geophysical quantities. Similarly, information on bulk geologic variations of size greater than a few hundred km is difficult to obtain through routine geologic techniques. This is the scale at which satellite magnetic and gravity data from CHAMP can find its niche in the lithospheric interpretation.

Satellite data can be used to help fill the coverage gaps in regional compilations of these near-surface surveys. For the near-surface Antarctic magnetic anomaly map being produced by the Antarctic Digital Magnetic Anomaly Project (ADMAP), we show that near-surface magnetic anomaly estimation is greatly enhanced by the joint inversion of the near-surface data with the CHAMP observations relative to the data from the Magsat and Orsted missions that respectively suffer from lower measurement accuracy and higher orbital altitudes. The analysis also suggests that considerable new insights on the magnetic properties of the lithosphere may be revealed by a further order-of-magnitude improvement in the accuracy of the magnetometer measurements at minimum orbital altitude.

CHAMP free-air gravity estimates at 400 km altitude suggest that previous gravity models may have regionally overestimated the anomaly field of Antarctica by roughly 5 mGals. The free-air anomalies can be separated into terrain-correlated and terrain-decorrelated components using the correlation spectrum with the computed terrain gravity effects. Analysis of the terrain-correlated anomalies together with the terrain effects reveals anomalously thinned crust beneath East Antarctica between the Gamburtsev and Transantarctic Mountains that includes Wilkes Land. These results suggest tectonically extended crust for roughly a third of East Antarctica as important new constraints on Gondwana dynamics. Additionally, the terrain-decorrelated free-air anomalies reveal mass variations of the mantle and core to constrain the thermodynamics of the subcrust, the origin of the geomagnetic field, and standard precession and nutation models. With CHAMP, we also have for the first time co-registered complementary magnetic and gravity observations. Hence, we can identify and study regionally correlative lithospheric mass and magnetization variations via Poisson's relationship for new constraint on regional petrological, structural, and thermal variations of the Antarctic lithosphere JF - First CHAMP mission results for gravity, magnetic and atmospheric studies AU - von Frese, Ralph R B AU - Potts, Laramie V AU - Kim, Hyung Rae AU - Shum, C K AU - Taylor, Patrick T AU - Kim, Jeong Woo AU - Han, Shin-Chan A2 - Reigber, Christopher A2 - Luehr, Hermann A2 - Schwintzer, Peter Y1 - 2003 PY - 2003 DA - 2003 PB - Springer-Verlag, Berlin SN - 3540002065 KW - Transantarctic Mountains KW - Southern Ocean KW - West Antarctica KW - volcanic rocks KW - geophysical surveys KW - igneous rocks KW - mantle KW - Cenozoic KW - gravity methods KW - gravity anomalies KW - gravity field KW - volcanism KW - Ross Sea KW - CHAMP KW - Gondwana KW - mantle plumes KW - free-air anomalies KW - rift zones KW - geophysical methods KW - magnetic methods KW - magnetic anomalies KW - correlation KW - satellite methods KW - paleogeography KW - models KW - continental drift KW - Antarctica KW - surveys KW - crust KW - remote sensing KW - Marie Byrd Land KW - 18:Solid-earth geophysics KW - 20:Applied geophysics UR - http://libproxy.lib.unc.edu/login?url=http://search.proquest.com/docview/51334328?accountid=14244 L2 - http://vb3lk7eb4t.search.serialssolutions.com/?ctx_ver=Z39.88-2004&ctx_enc=info:ofi/enc:UTF-8&rfr_id=info:sid/GeoRef&rft_val_fmt=info:ofi/fmt:kev:mtx:book&rft.genre=book&rft.jtitle=&rft.atitle=&rft.au=von+Frese%2C+Ralph+R+B%3BPotts%2C+Laramie+V%3BKim%2C+Hyung+Rae%3BShum%2C+C+K%3BTaylor%2C+Patrick+T%3BKim%2C+Jeong+Woo%3BHan%2C+Shin-Chan&rft.aulast=von+Frese&rft.aufirst=Ralph+R&rft.date=2003-01-01&rft.volume=&rft.issue=&rft.spage=&rft.isbn=3540002065&rft.btitle=CHAMP+gravity+anomalies+over+Antarctica&rft.title=CHAMP+gravity+anomalies+over+Antarctica&rft.issn=&rft_id=info:doi/ LA - English DB - GeoRef N1 - Copyright - GeoRef, Copyright 2012, American Geosciences Institute.

Subsequent studies, however, soon revealed that Magsat was able to map crustal magnetic anomalies. One of these investigations was centered on the Kursk Magnetic Anomaly (KMA) of Russia. Not only did this earlier Magsat study of the KMA record its magnetic signature at satellite altitude but also it was revealed that the anomaly displayed a significant component of remanent magnetization. With the subsequent launch of the higher altitude Orsted satellite a comparison between the KMA and these newer magnetic anomaly data was made. It was determined that Orsted could indeed record the crustal magnetic field and with a greater signal/noise ratio than Magsat since at a higher altitude the spacecraft was further from the ionosphere. It is not surprising, therefore, that after the successful launch of CHAMP we continued our initial study of the crustal anomaly field over the KMA with these newer magnetic observations. The KMA appears to be well represented in these CHAMP data as well.

Proterozoic gneisses and granitoid rocks underlie much of the quadrangle. They are overlain by upper Miocene basin-filling deposits of arkosic conglomerate, basalt, and the overlying Hualapai Limestone. Inception of the Colorado River followed deposition of the Hualapai Limestone and caused incision of the older rocks. Fluvial gravel deposits indicate various courses of the early river across passes through highlands of the Gold Butte-Hiller Mountains-White Hills structural block. Faults and tilted rocks in the quadrangle record tectonic extension that climaxed in middle Miocene time.

Large shear stresses within these layers support the majority of the gravitational driving stress within a fast-flowing ice stream. The present contribution looks upstream, to the tributaries that feed ice-stream onsets, and considers the effects of both horizontal and vertical shear on their flow. Numerical and direct simulations of vertical and horizontal shear are used. Vertical shear, simulated using an anisotropic flow law, is of particular interest. We conclude that by isolating overlying ice from large-amplitude variations in bed elevation, "vertical shear margins" play an important role in sustaining relatively rapid tributary flow.

Because current spallation theory predicts that near-surface rocks are ideal candidates for planetary ejection and surface basalts are widely distributed throughout the rocky planets, we isolated spore-forming bacteria from the interior of near-subsurface basalt rocks collected in the Sonoran desert near Tucson, Arizona. Spores were found to inhabit basalt at very low concentrations (< or =28 colony-forming units/g) in these samples. Six isolates identified as being most closely related to Bacillus pumilus and one Bacillus subtilis isolate were recovered from near-subsurface basalt samples. Populations of purified spores prepared from the isolated strains were subjected to 254-nm UV and ballistics tests in order to assess their resistance to UV radiation and to extreme acceleration shock, two proposed lethal factors for spores during interplanetary transfer. Specific natural isolates of B. pumilus were found to be substantially more resistant to UV and extreme acceleration that were reference laboratory strains of B. subtilis, the benchmark organism, suggesting that spores of environmental B. pumilus isolates may be more likely to survive the rigors of interplanetary transfer.

The presence of sulfur in three oxidation states indicates a complex series of redox reactions. Physical and chemical conditions of the spring water and surrounding environment, as well as mineralogical and isotopic signatures, suggest biologically mediated reactions. Cell counts and DNA analyses confirm bacteria are present in the spring system, and a limited number of sequenced isolates suggests that complex communities of bacteria live within the glacial system.

As a result of this discovery, and the ensuing controversy, it has become apparent that our knowledge of the early development of life on Earth is limited. Archean stratigraphic successions containing evidence of Earth's early biosphere are well preserved in the Pilbara Craton of Western Australia. The craton includes part of a protocontinent consisting of granitoid complexes that were emplaced into, and overlain by, a 3.51-2.94 Ga volcanigenic carapace-the Pilbara Supergroup. The craton is overlain by younger supracrustal basins that form a time series recording Earth history from approximately 2.8 Ga to approximately 1.9 Ga. It is proposed that a well-documented suite of these ancient rocks be collected as reference material for Archean and astrobiological research. All samples would be collected in a well-defined geological context in order to build a framework to test models for the early evolution of life on Earth and to develop protocols for the search for life on other planets.

Further more, forest-facing tree-bark contains significantly more magnetic particles than road-facing tree-bark. Magnetic particles were detected both on the bark of the maple trees and in the first centimeter of the soil cover (O/A horizon). Stability of saturation isothermal magnetization (SIRM) and hysteresis parameters of the soil indicates the presence of single domain (SD/PSD) magnetic carriers. Measurements of the tree bark hysteresis parameters and SIRM detect a significant lower coercivity component that we interpret to be an indication of more abundant pseudo-single domain (PSD) type magnetic grains. Magnetic measurements around the perimeters of eight tree trunks reveal magnetic carriers whose distribution is antipodal to the source direction (highway). We interpret our observation by adopting an air circulation model, where suspended PSD/SD particles are carried in the air stream. The air stream from the heavy traffic lowers the amount of moisture on the tree trunk surfaces facing the highway and thus reduces an adhesive potential on this side. Therefore, more particles can stay on the moist side of the trunk protected from the direct airflow.

Was Mars ever a warm and wet planet, or has it always been cold and dry? The study of surface depressions, in conjunction with river features, yields new insight into these questions. Together, these features provide a more complete picture of a surface water network that may have existed on what must have been a warmer early Mars.

The W isotope signature of lunar and martian basalts appears to be correlated to characteristics of their source. On the Moon, the small amount of excess (super 182) W is associated with basalts that may be derived from an ilmenite- and clinopyroxene-bearing mantle that was produced during late-stages of lunar magma ocean crystallization. On Mars, excess (super 182) W is associated with a depleted mantle source. Our experimental measurements for the partitioning behavior of Hf and W between silicates and melt suggest that the early fractionation of Hf from W by phases such as ilmenite, high-Ca clinopyroxene, and garnet may be significant enough to account for the generation of all or part of the radiogenic W signatures in the mantle sources for these basalts. The duration and nature of early mantle differentiation events on the Moon and Mars may be calculated by combining Hf-W fractionation with the extent of radiogenic W enrichment.

Extensive experimental studies of the partitioning of these elements between metallic liquid and silicate melt have led to a better understanding and a more sophisticated application to planetary problems. Siderophile element metal/silicate partition coefficients are a function of temperature, pressure, oxygen fugacity, and metal and silicate composition. Quantification of these effects for a limited subset of siderophile elements has led to the idea that early Earth had a 700-km or deeper magma ocean. This new understanding of siderophile element partitioning has also led to applications to the kinetics of metal-silicate equilibrium, links to the timing of core formation, and a better understanding of core formation and metal-silicate equilibrium in the Moon and Mars. Key issues for future consideration include the role of water in early Earth, consideration of the core as a reservoir for noble gases and/or traditionally lithophile elements, siderophile element concentrations in the deep mantle, oxygen fugacity at high pressures, and further evaluation of the need for a late accretional veneer. The strongest approach to improving accretion models for the terrestrial planets is one that combines geochemistry, geophysics, and planetary dynamics.

This review is structured around three related questions: Is the magnetite in ALH84001 of biological or non-biological origin, or a mixture of both? Does magnetite on Earth provide insight to the plausibility of biogenic magnetite on Mars? Could magnetotaxis have developed on Mars? There are credible arguments for both the biological and non-biological origin of the magnetite in ALH84001, and we suggest that more studies of ALH84001, extensive laboratory simulations of non-biological magnetite formation, as well as further studies of magnetotactic bacteria on Earth will be required to further address this question. Magnetite grains produced by bacteria could provide one of the few inorganic traces of past bacterial life on Mars that could be recovered from surface soils and sediments. If there was biogenic magnetite on Mars in sufficient abundance to leave fossil remains in the volcanic rocks of ALH84001, then it is likely that better-preserved magnetite will be found in sedimentary deposits on Mars. Deposits in ancient lakebeds could contain well-preserved chains of magnetite clearly indicating a biogenic origin.

Heat of combustion data can be used to estimate the lower flammability limit, upper flammability limit and minimum oxygen concentration for flame propagation of organic and organosilicon compounds. The data can also be used to assess the threshold oxygen pressure for the combustion of metal alloys in high-pressure oxygen environments.

We explored the phylogenetic and functional diversity of the sulfate-reducing bacteria by characterizing PCR-amplified dissimilatory sulfite reductase (dsrAB) and 16S rRNA genes from the upper 4 cm of the Guaymas sediment. The dsrAB sequences revealed that there was a major clade closely related to the acetate-oxidizing delta-proteobacterial genus Desulfobacter and a clade of novel, deeply branching dsr sequences related to environmental dsr sequences from marine sediments in Aarhus Bay and Kysing Fjord (Denmark). Other dsr clones were affiliated with gram-positive thermophilic sulfate reducers (genus Desulfotomaculum) and the delta-proteobacterial species Desulforhabdus amnigena and Thermodesulforhabdus norvegica. Phylogenetic analysis of 16S rRNAs from the same environmental samples resulted in identification of four clones affiliated with Desulfobacterium niacini, a member of the acetate-oxidizing, nutritionally versatile genus Desulfobacterium, and one clone related to Desulfobacula toluolica and Desulfotignum balticum. Other bacterial 16S rRNA bacterial phylotypes were represented by non-sulfate reducers and uncultured lineages with unknown physiology, like OP9, OP8, as well as a group with no clear affiliation. In summary, analyses of both 16S rRNA and dsrAB clone libraries resulted in identification of members of the Desulfobacteriales in the Guaymas sediments. In addition, the dsrAB sequencing approach revealed a novel group of sulfate-reducing prokaryotes that could not be identified by 16S rRNA sequencing.

We investigate whether reported PETM paleotemperature and paleo-CO sub(2) proxies are consistent with this hypothesis by considering the impact of large increases in CH sub(4) emissions to the atmosphere. Significant effects on atmospheric chemistry and CH sub(4) lifetime are seen for a range of plausible emission rates (1500 Gt carbon over 500-20,000 years). The resulting peak anomalous radiative forcing is 1.5-13.3 W/m super(2) depending on the emission scenario. The scenarios most closely matched to the PETM carbon isotope excursion have peak forcing of around 3 W/m super(2), which translates to peak temperature changes as a function of latitude that are a reasonable match to derived estimates. High CH sub(4) levels and enhanced stratospheric water vapor amounts persist for as long as do the emissions and are responsible for more of the peak radiative forcing than CO sub(2) levels, although results are sensitive to the background climate state and base CH sub(4) concentration.

Most models of accident causation are based on the notion that human errors occur in the context of contributing factors. However, there is a lack of published information on possible links between specific errors and contributing factors. A total of 619 safety occurrences involving aircraft maintenance were reported using a self-completed questionnaire. Of these occurrences, 96% were related to the actions of maintenance personnel. The types of errors that were involved, and the contributing factors associated with those actions, were determined. Each type of error was associated with a particular set of contributing factors and with specific occurrence outcomes. Among the associations were links between memory lapses and fatigue and between rule violations and time pressure. Potential applications of this research include assisting with the design of accident prevention strategies, the estimation of human error probabilities, and the monitoring of organizational safety performance.

It is a Gram-positive, facultatively anaerobic, rod-shaped eubacterium that produces endospores. The spores of this novel bacterial species exhibited resistance to UV, gamma -radiation, H sub(2)O sub(2) and desiccation. The 16S rDNA sequence analysis revealed a clear affiliation between this strain and members of the low G + C Firmicutes. High 16S rDNA sequence similarity values were found with members of the genus Bacillus and this was supported by fatty acid profiles. The 16S rDNA sequence similarity between strain FO-92 super(T) and Bacillus benzoevorans DSM 5391 super(T) was very high. However, molecular characterizations employing small-subunit 16S rDNA sequences were at the limits of resolution for the differentiation of species in this genus, but DNA-DNA hybridization data support the proposal of FO-92 super(T) as Bacillus nealsonii sp. nov. (type strain is FO-92 super(T) =ATCC BAA-519 super(T) =DSM 15077 super(T)).

Understanding the direction and rates of changes in scrub composition and structure after fire is important to management decisions. We followed changes in vegetation along 15-m line-intercept transects that were established in 1983. Two stands (8 transects) burned in a prescribed fire in December 1986; the stands had previously burned 11 y (N=4) and 7 y (N=4) before. We sampled transects at 6, 12, 18, and 24 mo and then annually through 10 y after the 1986 fire. We measured cover by species in two height classes, > 0.5 m and 0.5 m (Quercus myrtifolia, Q. geminata, Q. chapmanii) equaled preburn values by 5 y postburn and changed little by 10 y postburn. Height growth continued, increasing from a mean of 84.0 cm at 5 y to 125.9 cm at 10 y postburn. Bare ground declined to <2% by 3 y postburn. Plant species richness increased slightly after fire and then gradually declined. These vegetation changes alter habitat conditions for threatened and endangered animals and plants.

We consider the conservation status of the fisher (Martes pennanti) and evaluate the potential genetic consequences of past and future translocations on this medium-sized carnivore by examining population variation in mitochondrial control-region sequences. We sampled populations throughout the fisher's range in North America including five populations unaffected by translocations and two western populations that had received long-distance translocations. Twelve haplotypes showed little sequence divergence. Haplotype frequencies differed significantly among subspecies and between populations within subspecies. Analysis of molecular variance (amova) and neighbour-joining analyses of haplotype relationships revealed population subdivision similar to current subspecies designations, but which may reflect an isolation-by-distance pattern. Populations in Oregon and in Montana and Idaho received several translocations and each showed greater similarity to the populations where translocations originated than to adjacent populations. Additional sequences obtained from museum specimens collected prior to any translocations suggest historical gene flow among populations in British Columbia, Washington, Oregon, and California. Anthropogenic impacts in that region have greatly reduced and isolated extant populations in Oregon and California. Future translocations may be necessary to recover populations in Washington and portions of Oregon and California; our results indicate that British Columbia would be the most appropriate source population.

Using constant-power sap flow gauges, we measured transpiration from Quercus myrtifolia Willd., the dominant species of the Florida scrub-oak ecosystem, which had been exposed in situ to elevated C sub(a) (350 mu mol mol super(-1) above ambient) in open-top chambers since May 1996. Elevated C sub(a) reduced average transpiration per unit leaf area by 37%, 48% and 49% in March, May and October 2000, respectively. Temporarily reversing the C sub(a) treatments showed that at least part of the reduction in transpiration was an immediate, reversible response to elevated C sub(a). However, there was also an apparent indirect effect of C sub(a) on transpiration: when transpiration in all plants was measured under common C sub(a), transpiration in elevated C sub(a)-grown plants was lower than that in plants grown in normal ambient C sub(a). Results from measurements of stomatal conductance (g sub(s)), leaf area index (LAI), canopy light interception and correlation between light and g sub(s) indicated that the direct, reversible C sub(a) effect on transpiration was due to changes in g sub(s) caused by C sub(a), and the indirect effect was caused mainly by greater self-shading resulting from enhanced LAI, not from stomatal acclimation. By reducing light penetration through the canopy, the enhanced self-shading at elevated C sub(a) decreased stomatal conductance and transpiration of leaves at the middle and bottom of canopy. This self-shading mechanism is likely to be important in ecosystems where LAI increases in response to elevated C sub(a).

NDVI is closely related to the amount of absorbed photosynthetically active radiation; hence, trends in NDVI reflect trends in photosynthetic activity of land-surface vegetation. Linear and nonlinear trend analysis techniques were applied to four differently processed and corrected Advanced Very High Resolution Radiometer (AVHRR) NDVI data sets. The results were compared in order to evaluate the effects of trends in NDVI unrelated to vegetation activity. We consistently found significant positive trends in averaged NDVI for latitude bands above 35 degree N in all but one data set; this one data set lacked corrections for sensor drift and instrument calibration. An impressive improvement in data quality was achieved by applying calibration and corrections for atmospheric effects. Conservative estimates of the trends over the 1982-99 period range from 0.0015 to 0.0045 NDVI units year super(-1) for global latitude bands from 35 to 75 degree N, with trends generally higher in the 1990s than in the 1980s; trends in NDVI were larger than trends explained by artefacts. In the 1980s, North American and Eurasian trends were roughly comparable, whereas in the 1990s the North American trends were generally higher. A pixel-level analysis shows the trends to be widespread, with large areas of Canada, Europe and northern Asia experiencing significant positive increases across all vegetated landcovers.

POAM-III profiles showed the cloud was 9-12 km asl. During 3 days this cloud drifted north. Three remote sensing algorithms (TOMS SO (sub 2) , MODIS & TOVS 7.3 mu m IR and MODIS 8.6 mu m IR) estimated approximately 0.2 Tg SO (sub 2) . Sulfate aerosol in the cloud was 0.003-0.008 Tg, from MODIS IR data. MODIS and AVHRR show that cloud particles were ice. The ice mass peaked at approximately 1 Tg approximately 10 hours after eruption onset. A approximately 0.1 Tg mass of ash was detected in the early plume. Repetitive TOVS data showed a decrease of SO (sub 2) in the cloud from 0.2 Tg to below TOVS detection (i.e. <0.01 Tg) in approximately 3.5 days. The stratospheric height of the cloud may result from a large release of magmatic water vapor early (1819 UT on 26 February) leading to the ice-rich volcanic cloud. The optical depth of the cloud peaked early on 27 February and faded with time, apparently as ice fell out. A research aircraft encounter with the top of the cloud at 0514 UT on 28 February, 35 hours after eruption onset, provided validation of algorithms. The aircraft's instruments measured approximately 0.5-1 ppmv SO (sub 2) and approximately 35-70 ppb sulfate aerosol in the cloud, 10-30% lower than concentrations from retrievals a few hours later. Different SO (sub 2) algorithms illuminate environmental variables which affect the quality of results. Overall this is the most robust data set ever analyzed from the first few days of stratospheric residence of a volcanic cloud.

These include three LIDAR aerosol backscatter measurements, at Mauna Loa Observatory (Hawaii), Langley Research Center (Virginia), and Garmisch-Partenkirchen (Germany); balloonborne in situ particle concentration measurements at Laramie, Wyoming, solar visible transmission measurements at Mauna Loa Observatory; aerosol optical depth measurements at South Pole Station and Mauna Loa Observatory; and lunar eclipse optical depth determinations, which is a globally integrating technique. Surface-based measurements have provided a useful historical record of volcanic effects on the stratospheric aerosol and the agreement between the various techniques is very good. However, some uncertainties exist when the stratosphere is relatively free of volcanic aerosol and some of the techniques are not able to easily resolve the very small amount of aerosol from natural and/or anthropogenic sources. The lunar eclipse data, which go back to the late 1800s, suggest that the Pinatubo eruption in 1991 probably perturbed the stratospheric aerosol layer at least as much as that of Krakatau in 1883. This is an important observation as it is one of the few ways to accurately compare the stratospheric effects of eruptions prior to modern measurements that began in the late 1950s. At the time of this writing (September 2002) the stratosphere appears to be at background with the lowest level of aerosol observed since the layer was discovered in 1959.

Since iron goes through corrosion reactions during the remediation process, precipitates form on the iron surface thus leaving the permeable reactive barrier less effective and can even alter groundwater flow around the wall. After several years of laboratory study, ultrasound was used at two different PRB field sites. Results show that ultrasound application improves half-lives from 21-67% (dependent on transducer power and duration of exposure) over untreated iron samples from the same PRB treatment site.

The emulsified system consisted of a surfactant-stabilized, biodegradable oil-in-water emulsion with nanoscale or microscale iron particles contained within the emulsion droplets. It was demonstrated that DNAPLs, such as TCE, diffuse through the oil/surfactant membrane of the emulsion particle whereupon they reach an aqueous interior and the surface of an iron particle where dehalogenation takes place. The hydrocarbon reaction by-products of the dehalogenation reaction, primarily ethene (no chlorinated products detected), diffuse out of the emulsion droplet. This study also demonstrated that an iron-emulsion system could be delivered in-situ to the DNAPL pool in a soil matrix by using a simulated push well technique. Iron emulsions degraded pure TCE at a rate comparable to the degradation of dissolved phase TCE by iron particles, while pure iron had a very low degradation rate for free-phase TCE. The iron-emulsion systems can be injected into a sand matrix where they become immobilized and are not moved by flowing water. It has been documented that surfactant micelles possess the ability to pull pooled TCE into emulsion droplets where degradation of TCE takes place.

Low-density polyimide foam exhibits a high ignition resistance. The minimum heat flux for the ignition of flaming combustion ranges from 48 to 54 kW/m super(2). This minimum heat flux also indicates the heat flux for transition from smoldering to flaming combustion. The flaming combustion results show that the heat release rate of low-density polyimide foam is very low even at a high incident heat flux of 75 kW/m super(2). The smoldering combustion results show that the smoldering of low-density polyimide foam becomes significant when the incident heat flux is greater than 30 kW/m super(2). The smoldering combustion of low-density polyimide foam cannot be self-sustaining when the external heat source is removed.

Use of a chemically defined medium (C. elegans Maintenance Medium (CeMM)) now allows standardization and systematic manipulation of the nutrients that animals receive. Liquid cultivation allows automated culturing and experimentation and should be of use in large-scale growth and screening of animals. We find that CeMM is versatile and culturing is simple. CeMM can be used in a solid or liquid state, it can be stored unused for at least a year, unattended actively growing cultures may be maintained longer than with standard techniques, and standard C. elegans protocols work well with animals grown in defined medium. We also find that there are caveats to using defined medium. Animals in defined medium grow more slowly than on standard medium, appear to display adaptation to the defined medium, and display altered growth rates as they change the composition of the defined medium. As was suggested with the introduction of C. elegans as a potential genetic system, use of defined medium with C. elegans should prove a powerful tool.

Repeated airborne laser-altimeter surveys along a 120 km profile in the glacier basin show slow, sporadic thickening between 1991 and 1997, suggesting a small positive mass balance, but since 1997 there has been sustained thinning of several m a super(-1) within 20 km of the ice front, with lower rates of thinning further inland. Here, we use weather-station data from the coast and the ice sheet to estimate the effects on surface elevation of interannual variability in snowfall and surface melt rates, and thus to infer the temporal and spatial patterns of dynamic thinning. These show the glacier to have been close to balance before 1997 followed by a sudden transition to rapid thinning, initially confined to the lower reaches of the glacier (below about 500 m elevation), but progressively spreading inland until, between 1999 and 2001, thinning predominated over the entire surveyed region, up to 2000 m elevation. If this continues, the glacier calving front and probably its grounding line will retreat substantially in the very near future.

Eucritic clasts were derived from cumulate eucrites, main-group eucrites, and evolved eucrites that are more Fe-rich than Nuevo Laredo, and include unequilibrated and equilibrated materials. Several of the diogenitic clasts are orthopyroxenite breccias that are much finer-grained than typical diogenites. Bulk compositions and mineral compositions of matrix and clasts indicate that EET 87513 can be modeled as a mixture, by weight, of 30% diogenite, 17% cumulate eucrite, 25% main-group eucrite, 25% Nuevo Laredo-trend eucrite, and 3% CM, chondrite. The character of this mixture is probably related to the depth of excavation by impact processes on Vesta and these meteorites may be appropriate as approximate analogues for portions of the surface regolith. The relatively large proportion of CM, material in this mixture, compared with the relatively small number of carbonaceous chondrite clasts observed in thin sections, suggests that much of this CM, material is present as sub-microscopic particles between individual mineral fragments and clasts.

As is frequently the case in agriculture, available ground-based leaf area measurements employed by growers are not well suited to larger area mapping. In this study, IKONOS high spatial resolution, multispectral satellite imagery was used to map leaf area throughout two commercial wine grape vineyards (approximately 800 ha) in California's North Coast growing region. The imagery was collected near harvest during the 2000 growing season, converted to at-sensor radiance, geo-referenced and transformed to normalized difference vegetation index (NDVI) on a per pixel basis. Measurements at 24 ground calibration sites were used to convert NDVI maps to leaf area index (LAI; m super(2) leaf area m super(-2) ground area); planting density was then used to express leaf area on a per vine basis (LA sub(v)). Image-based LA sub(v) was significantly correlated with ground-based LA sub(v) estimates developed at 23 validation sites (r super(2) = 0.72; P < 0.001). Despite challenges posed by the discontinuous nature of vineyard canopies and architectural differences imposed by shoot positioning trellis systems, remote sensing appears to offer a basis for mapping vineyard leaf area in low LAI vineyards. Such maps can potentially be used to parameterize plant growth models or provide decision support for irrigation and canopy management.

Ice temperature was modeled with a simple vertical advection-diffusion equation, "tuned" to match temperature profiles. We find that most of the melt occurs beneath the tributaries, where larger basal shear stresses and thicker ice favor greater melt (e.g. 10-20 mm a super(-1)). The occurrence of basal freezing is predicted beneath much of the ice plains of Ice Stream C and Whillans Ice Stream. Modeled melt rates for when Ice Stream C was active suggest there was enough meltwater generated in its tributaries to balance basal freezing on its ice plain. Net basal melt for Whillans Ice Stream is greater due to less steep basal temperature gradients. Modeled temperatures on Whillans Ice Stream, however, were constrained by a single temperature profile at UpB. Basal temperature gradients for Whillans branch 1 and Ice Stream A may have conditions more similar to those beneath Ice Streams C and D, in which case, there may not be sufficient melt to sustain motion. This would be consistent with the steady deceleration of Whillans Ice Stream over the last few decades.

In those cases, the mode is a better estimator of the overall time of divergence than the mean or median. However, different methods are available for estimating the mode. We compared these methods in simulations to determine their strengths and weaknesses and further assessed their performance when applied to real data sets from a molecular clock study. Results: We found that the half-range mode and robust parametric mode methods have a lower bias than other mode methods under a diversity of conditions. However, the half-range mode suffers from a relatively high variance and the robust parametric mode is more susceptible to bias by outliers. We determined that bootstrapping reduces the variance of both mode estimators. Application of the different methods to real data sets yielded results that were concordant with the simulations. Conclusions: Because the half-range mode is a simple and fast method, and produced less bias overall in our simulations, we recommend the bootstrapped version of it as a general-purpose mode estimator and suggest a bootstrap method for obtaining the standard error and 95% confidence interval of the mode.

These are contrasted with sensitivities of barotropic vorticity. Forecast periods between 1 and 24 h are investigated. Root-mean-square values of the sensitivities as a function of vertical coordinate and field are presented as well as time series of impacts of optimal perturbations weighted by initial variances of uncertainties in the fields. For all the forecast aspects and cases considered, the greatest sensitivity and impacts are with regard to the temperature field. Precipitation is equally sensitive to vorticity and divergence, but when their relative uncertainties are considered, impacts of the vorticity dominate those of divergence. Precipitation is sensitive to initial specific humidity, but so is barotropic vorticity within a cyclone. The sensitivities of precipitation were not found to increase with forecast periods as much as the sensitivities to vorticity, suggesting that even within the same synoptic feature, different processes are responsible for the development of these distinct characteristics. Although comparison with corresponding impacts in the nonlinear model suggests that a 24 h period is too long for the adjoint-estimated precipitation impacts to be good approximations to the nonlinear results in some of the cases, 6-h adjoint-estimated results appear useful.

The amplitudes of the seasonal variations decrease from west to east and from south to north, determined by the accumulation rate and the surface-temperature distribution pattern. Several methods of estimating the amplitude of the seasonal variation in the observations are compared, including the use of a three-frequency sinusoidal function derived from the modeled seasonal variation that is asymmetric. The resulting correlation coefficient between the observed amplitude, estimated with the three-frequency function, and the modeled amplitude is 0.66 and the slope is 0.7. Residual differences may be caused by interannual variability in accumulation and temperature and other approximations in the model.

During a spring-tide period, rapid motions regularly occur near high tide and during falling tide. This correlation is weaker during a neap-tide period when the tidal magnitudes are less. Precise timing of these motion events suggests that they propagate through the region with a mean velocity of 88 m s super(-1). We hypothesize that this speed is associated with the propagation of shear waves through a wet subglacial till. Motion events are also seen on more smoothly flowing floating ice. Event delays are very short between grounded and floating stations, suggesting the events propagate through the ice shelf as an elastic wave. We further hypothesize the events are caused by the interaction of a sticky bed, the accumulation of stored elastic strain through the compression of ice by upstream inflow, and tidal forcing. Motion events seem to be triggered either by reduction of vertical normal stresses at high tide or by the increase of shear stresses from sub-shelf ocean currents during falling tide. Event magnitudes are not related to the length of the preceding quiescent period, suggesting significant viscous dissipation within the till.

One path is near the centre line of the main tributary to the ice stream, while the second passes by the Byrd Station borehole site. In this paper, we analyze the flow of the moderately fast-flowing tributaries in terms of ice-fabric anisotropy and estimate the steady-state ice-flow regions with the compatible developed crystal orientation fabrics along two particle paths. Comparison between modelled isochrones and internal layers detected from radio-echo sounding surveys in the area is used to suggest that flow upstream of the onset to Ice Stream D appears to have been stable since at least the Last Glacial Maximum.

Tropospheric variability and the zonal wave-one AN - 16145190; 5571514 AB - The first view of stratospheric and tropospheric ozone variability in the Southern Hemisphere tropics is provided by a 3-year record of ozone soundings from the Southern Hemisphere Additional Ozonesondes (SHADOZ) network (http://croc.gsfc.nasa.gov/shadoz). Observations covering 1998-2000 were made over Ascension Island, Nairobi (Kenya), Irene (South Africa), Reunion Island, Watukosek (Java), Fiji, Tahiti, American Samoa, San Cristobal (Galapagos), and Natal (Brazil). Total, stratospheric, and tropospheric column ozone amounts usually peak between August and November. Other features are a persistent zonal wave-one pattern in total column ozone and signatures of the quasi-biennial oscillation (QBO) in stratospheric ozone. The wave-one is due to a greater concentration of free tropospheric ozone over the tropical Atlantic than the Pacific and appears to be associated with tropical general circulation and seasonal pollution from biomass burning. Tropospheric ozone over the Indian and Pacific Oceans displays influences of the waning 1997-1998 El Nino, seasonal convection, and pollution transport from Africa. The most distinctive feature of SHADOZ tropospheric ozone is variability in the data, e.g. a factor of 3 in column amount at 8 of 10 stations. Seasonal and monthly means may not be robust quantities because statistics are frequently not Gaussian even at sites that are always in tropical air. Models and satellite retrievals should be evaluated on their capability for reproducing tropospheric variability and fine structure. A 1999-2000 ozone record from Paramaribo, Surinam (6 degree N, 55 degree W) (also in SHADOZ) shows a marked contrast to southern tropical ozone because Surinam is often north of the Intertropical Convergence Zone (ITCZ). A more representative tropospheric ozone climatology for models and satellite retrievals requires additional Northern Hemisphere tropical data. JF - Journal of Geophysical Research. D.
